New design for inferential control system (English)
0 references
An \(H_\infty\) optimal controller is considered for systems with infrequently sampled output. Based on the proposed I/O model, unmeasurable primary outputs can be inferred and the controller can be designed directly, so that the inferential estimator and the controller can be linked together and calculation is considerably simplified. By the polynomial equation method, the \(H_\infty\) optimal control law is derived from the LQG control law. The robustness of the inferential control system is explicitly expressed by the sensitivity. This controller is also suitable for nonminimum-phase and unstable plants.
