This paper proposes a new algorithm that finds fuzzy control law of the system in which little knowledge has been known. In view or conventional fuzzy method, making control law needs the sense and the knowledge of the system which are provided by expert. But fuzzy control using proposed algorithm needs no expert for hating control law. After construction of the 1st order approximated ARMA model using input-output pairs, new defuzzification method is applied. The deduced rule is stored in fuzzy input space and updated by the proposed algorithm adaptively. To show the validity and effectiveness of proposed control method. simulation result is presented.

China has recently (28 August 2004) adopted a new act legalizing the electronic signature. This new act provides electronic signatures with the same legal status as handwritten signatures, and states that on-line certification providers will have to be created in order to ensure the security of on-line operations made using said signatures. This new act is intended to increase Chinese electronic business, and thus to raise the revenue China can expect from said business. And the law grants electronic signatures the same legal effect as handwritten signatures and seals in business transactions, and sets up the market access system for online certification providers to ensure the security of e-commerce. As Internet trade requires a reliable third party to identify the signers, the credibility of online certifying organizations is significant for the transaction security. So, considering the weakness of China's social credibility system, the law regulates that the online signatures certification providers should be approved and administered by governments.

The equations of motion for a basic industrial robotic system which has a rigid or a flexible arm are derived by Lagrange's equation, respectively. Especially, for the deflection of the flexible arm, the assumed mode method is employed. These equations are highly nonlinear equations with nonlinear coupling between the variables of motion. In order to design the control law for the rigid-arm robot, Hunt-Su's nonlinear transformation method and Marino's feedback equivalence condition are used with linear quadratic regulator(LQR) theory. The control law for the rigid-arm robot is employed to input the desired path and to provide the required nonlinear transformations for the flexible-arm robot to follow. By using the implicit Euler method to solve the nonlinear equations, the comparison of the motions between the flexible and the rigid robots and the effect of flexibility are examined.

A recurrent adaptive model-free intelligent control with a friction estimation law is proposed to enhance the positioning performance of the mover in PMLSM system. For the PMLSM with nonlinear friction and uncertainty, an adaptive recurrent fuzzy neural network(ARFNN) and compensated control law in $H_{\infty}$ performance criterion are designed to mimic a perfect control law and compensate the approximated error between ideal controller and ARFNN. Combined with friction observer to estimate nonlinear friction parameters of the LuGre model, on-line adaptive laws of the controller and observer are derived based on the Lyapunov stability criterion. To analyze the effectiveness our control scheme, some simulations for the PMLSM with nonlinear friction and uncertainty were executed.

Recently the renewable energy has been used widely and the importance of renewable sources is bigger than before. So the government enforced a law to the public buildings to install the renewable energy facilities. The capacity of facilities is 5% of total construction cost until April 13, 2011. Since then, the government changed the law from 5% of total construction cost to 10% of predicted energy usage because of the practical use of the renewable energy facilities. So, in this study, the comparative analysis is conducted according to the law to the building installed PV system through the EnergyPlus simulation.

This paper proposed the new control law which is defined by instantaneous output and time delayed output. To analyze the system with time delayed output, the way which transforms output time delayed systEms into instantaneous output systems is presented. The output responses were more improved by the new control law thEn that of the instantaneous output control law. The algorithem for simulation and a numerical exemple are presented.

This paper presented here contains development of variable stability system(VSS) control laws for the KIFS (Korean In-Flight Simulator) aircraft to simulate the dynamics of F-16 aircraft. Development of VSS Control law for pitch rate, roll rate, yaw rate simulation for three specified flight conditions using Model Following Technique with rate feedback autopilot for stability provision. The direct lift force controller was also added to the developed VSS control law to simulate the pitch rate and normal g-load simultaneously. The simulation results show high accuracy of F-16 aircraft's pitch, roll, yaw rate and g-load simulation.

The general time optimal control law provides the optimal solution for a minimum time control problem. But in most real systems with disturbances and model uncertainties, the time optimal control law leads to chattering effect. This chattering effect can cause the system to be unstable. Therefore, we propose a robust optimal control algorithm for the nonlinear second order systems with model uncertainty. The proposed algorithm is combined with bang-bang control and sliding mode control. Thus the proposed algorithm has two state space regions to implement to control algorithm. In each region, the appropriate linear or nonlinear feedback control law is used satisfying the dynamic system equations. Simulation results show the superiority of the proposed controller in comparison with pure time optimal control(bang-bang control).

1994년 "유엔해양법협약" 의 발효로 새로운 국제해양법제도가 확립되면서 세계 각국은 통일적인 해상집법체제를 구축함으로써 관할해역에 대한 종합적인 관리를 강화하고 있다. 그러나 중국은 아직 전통적인 분산형 산업관리체제를 유지하고 있어 기존의 해상집법역량은 날로 확대되는 국가주권과 해양권익의 수호요구를 충족시키지 못하고 있다. 따라서 본 연구에서는 한 중 일 3국의 해상집법체제를 비교 고찰하고 중국해상집법체제의 주요 문제점을 분석한 후, 해경을 중심으로 한 통일적인 해상집법체제의 개선방안을 제시하였다.

Currently, it is the general trend that the party's autonomy principle is applicable in determining the applicable law for the international private law and the international commercial arbitration. The purpose of this article is to make research on the party's autonomy principle for the international commercial arbitral awards. For this purpose ist to analyse regal issue the applicability of the lex mercatoria and the possibility of $d\acute{e}pe\c{c}age$ relating to the party autonomy. In this Article ist dealt with Art. 29 para. 1 of the Korean Arbitration Act in comparison with Art. 28 para. 1 UNCITRAL Model Law and Art. 1051 para. 1 of the German Code of Civil Procedure. The Art. 28 para. 1 UNCITRAL Model Law and Art. 1051 para. 1 of the German Code of Civil Procedure provides equally. "The arbitral tribunal shall decide the dispute in accordence with such 'rules of law' as chosen by the parties as applicable to the substance of the dispute. Any designation of the law or legal system of a given State shall be construed, unless otherwise expressed, as directly referring to the substantive law of that State and not to its conflict of laws rules." The term 'rule of law' used to describe the applicability of the lex mercatoria and the possibility $d\acute{e}pe\c{c}age$. Unlike Art. 28 para. 1 UNCITRAL Model Law and Art. 1051 para.1 of the German Code of Civil Procedure. Act, Art. 29(1) of the Korean Arbitration Act provides that the arbitral tribunal shall decide the dispute in accordence with the 'law' chosen by the parties as applicable to the substance of the dispute. However the majority view in Korea takes the position that the term 'law' should be interpreted broadly so as to encompass 'rules of law' at UNCITRAL Model Law and the German Code of Civil Procedure.
