Abstract :
This paper considers the structural constrained controllers of mixed LQR/H∞ control problem in the general case. This problem involves two cases: One is a static output feedback case, another is a PID controller case. Necessary and sufficient conditions for the existence of all static output feedback controllers solving this problem are given. Also, two design procedures for solving mixed LQR/H∞ PID problem in complete state feedback and incomplete state feedback cases is respectively proposed.
