This paper presents a control scheme for the motion of a 2 DOF robot manipulator. Robot manipulators are multivariable nonlinear systems. Fuzzy logic is avaliable human-like control without complex mathematical operation and is suitable to nonlinear system control. In this paper, Implementation of fuzzy logic control of robotic manipulators shows. Algorithm has been performed with simulation packages MATRIXx and SystemBuild.

A real tine simulator of running power train for a construction vehicle was developed. The simulator mainly consists of following two parts; (1) running power train part and (2) running load generation part. An optimal servo control algorithm was adopted for designing the multi-variable digital control system of the simulator. By experiments investigating response characteristics under step-wise variation or pre-determined scenario of target vehicle velocity and target load torque, it was verified that the simulator could reproduce physical situations at and actual vehicle with excellent similarity.

The purposes of this paper are to deal with the design of m-input, m-output linear systems by the state variable feedback, and to extend the design capability of the state variable feedback design. The design requirements are decoupling and the exact realigation of desired transfer functions. Some methods are proposed to insert series compensators in the fixed plant in the cases when series compensators are needed to meet the input-output transfer matrix specification. The method for adding series compensators to the input channels of the fixed plant is shown by examples to lead both to the loss of the ability to decouple the augmented plant by the state variable feedback, and to the loss of desired zeroes. A method which avoids these two hazards is developed in which series compensators are put on the output channels of the fixed plant: it is proved that the augmented plant is F-invariant. By treating each subsystem individually, the designer can apply some of the previous developed knowledge of the state variable design of single-input, single-output systems.

초음속제트 엔진의 동적거동 모사를 수행하고 흡입구에서의 버즈 마진 확보와 추력 제어를 위한 PI 제어 알고리즘을 연구하였다. 먼저 연료유량 제어를 통해 요구추력을 추종하고 노즐 목 면적 제어를 통해 흡입구에서의 버즈마진이 항상 양의 수를 갖도록 흡입구 출구 압력을 조절하였다. 비행 마하 수, 고도, 받음각 변화에 따라 추력제어와 버즈 마진 제어를 위한 비례 게인과 적분 게인을 각각 구하고 시뮬레이션 하였다. 그 결과 비행 마하 수 2.1에서 3.0, 받음각 $0^{\circ}$에서 $10^{\circ}$ 사이의 운용영역에서 제어목표를 만족함을 확인하였다.
