Research Abstract

Stability and quality of control in feedback control systems under failure were analyzed, and design methods of the controller were developed, which preserve stability and quality of control under such circumstances as a break down in some of signal lines or parameter variations in plants. The main results are as follows:
1. A necessary and sufficient condition for integrity was derived in terms of the return difference matrix of a closed loop in normal operation. A series of design methods to realize integrity were developed.
2. A design method of a controller was developed, which preserves quality of control as well as integrity under failure in feedback loop.
3. A new concept of responsible control was proposed. It is a control scheme where each control agent is responsible in respective set of outputs. By this responsible control scheme, one can expect strong integrity.
4. A general stability condition for a system with time-delay was derived.
5. A general theory of an optimal regulator for a system with time-delay was developed.
6. A design tool for a controller possessing integrity was implemented in an in-house CAD system - ISSACS.
