The TRDI's FADEC technology has been matured within the JEC-series FADEC R&D programs. Topics are described that have involved Third Research Center, TRDI in the process of the JEC-series programs. The status of the TRDI's technology research and development, which determines the role of the engine control systems group and its research objectives, is briefly overviewed. Some important topics are described that are absorbing the group's research effort in accordance with such status.","PeriodicalId":344374,"journal":{"name":"SICE '95.

It is shown that any reduced-order observer based controller stabilizing the plant is unstable while full-order observer based controllers are stable. The self-sensing suspension in magnetic bearings with solid cores is also discussed. It is shown that the controllers are destabilized by a modification of the eddy currents flowing through the cores. It gives the reason for the difficulty of actual self-sensing suspension in the solid-cored magnetic bearing.","PeriodicalId":344374,"journal":{"name":"SICE '95.

A sufficient condition for maintaining observability in multirate sampled-data systems is given first. The design strategy for disturbance rejection is proposed. The proposed controller has IMC structure, and can be decomposed into a disturbance estimator and the inverse of the fast plant. The authors assume that the disturbance consists of a sum of finite number of sine waves with different frequencies and DC bias. Simple examples are presented for illustrations.","PeriodicalId":344374,"journal":{"name":"SICE '95. Proceedings of the 34th SICE Annual Conference.

By analyzing phase plane characteristics we can build and optimize the rule base of FLC. Variation of universe of discourse (UOD) can give coarse or fine control effects. With this variable UOD an adaptive gain tuning method is used to improve performance in transient and steady state. To show the improved performance of FLC and effectiveness of these methodologies, it is applied to design of attitude control system for a flexible spacecraft which has inherently a strong nonlinearities such as a hysteresis and a dead band.","PeriodicalId":344374,"journal":{"name":"SICE '95.

A parametric NN (PNN) can represent both linear and nonlinear relationships explicitly and simultaneously by setting its parameters appropriately. In many cases we have some information about the system which enable us to build a linear controller for it. But of course this is not enough for treating nonlinear plants. Using PNN we could make a complimentary linearized controller and then, after starting the learning, in an online manner it will be extended to a nonlinear dominant controller.","PeriodicalId":344374,"journal":{"name":"SICE '95.
