Abstract :
Shows that the decoupling control for MIMO control systems can be realized by introducing the concept of diagonal dominance and then regarding an index as relative evaluation for each block of closed loop transfer matrices. The closed loop transfer functions are divided into 2×2 blocks of the design and nondesign channels. In this paper we reach the conclusion that the decoupling problem for MIMO system is replaced by an optimization problem for a class of mixed sensitivity functions by regarding the closed loop interactive term as a multiplicative one. A decentralized controller is obtained by solving such the optimization problem for individual loops
