| Research Abstract |
The study clarifies the following results as the constructive stability and initial condition problem in supervisory control system.
(1) The stability of supervisory system should be considered, including the supervisor rule. Here, it is supposed to be the switching rule of two compensators. The stability is discussed with Liapunov function, so as the switching device is the nonlinear function.
First of all, the best or the worst switching rule for stability is clarified. Secondly constructive stability is invested based on the system characteristics such as the eigen values
(2) Nonholonomic system is dealt with as the examples of switched system and a design theory of stabilizable compensator is proved by using Liapunov function. It is applied to the steering control of a two-wheeler.
(3) The dynamical behavior of switched two tanks is analyzed and it is realized as chaotic behavior.
