The prevalence of microprocessor-based controllers in automotive systems has greatly increased the meed for tools which can be used to validate and test control systems over their full range of operation. The objective of this paper is to develop a real time simulator of an anti-lock braking system and the methodology of using hardware-in-the-loop simulation based on a personal computer. By use of this simulator, the analyses of a commercial electronic control unit as well as the validation of the developed control logics for ABS were performed successfully. The simulator of this research can be traction applied to development of more advanced control system, such as traction control systems, vehicle dynamic control system and so forth.

State dependent Riccati equation (SDRE) control technique has been widely used in the control society. Although it solves nonlinear optimal control problems, which minimizes state error and control efforts simultaneously, it has drawbacks when it is to be applied to the real time systems in that it requires much computational efforts. So the real time system whose computational ability is limited (for example, satellites) cannot afford to use SDRE controller. To solve this problem, a hybrid controller which is based on MSDRE (Modified SDRE) and ANFIS (Adaptive Neuro-Fuzzy Inference System) has been proposed by Abdelrahman et al. (2010). We propose a hybrid controller based on SDRE and ANFIS, and apply the hybrid controller to the hardware attitude simulator to perform a HIL (Hardware-In-the-Loop) simulation. Through HIL simulation, it is demonstrated that the hybrid controller satisfies the control requirement and the computation load is reduced significantly. In addition, the effects of statistical properties of the ANFIS training data to the performance of the ANFIS controller have been analyzed.

Hybrid Imprint Lithography (HIL) is proposed where photolithography and imprinting processes are employed. Fabrication step of multilevel or three dimensional patterns is suggested. The method of controlling residual layer thickness after imprinting is developed. The thickness of residual layer changes lineally with imprinting time and can be controlled. Polymer patterns fabricated by this HIL is demonstrated.
