BOTH STATE AND INPUT CONSTRAINED OPTIMIZATION OF A PEDESTAL POSITIONING SYSTEM

The optimization of a control system with a quadratic performance inde x subjected to both input and state constraints is a very complicated task. To the author's best knowledge, the general theoretical research es as well as the practical applications are quite few, because there exist many difficult or even more formidable obstacles in the real wor k. From a practical point of view based on security consideration, the se constraints are very important and should be observed strictly with out exception, otherwise the whole system might be destroyed and all c ontrol laws become nothing! This paper is devoted to the study of this complicated but very important problem: to find the optimal control w ith both state and input constrained.
