Sufficient Condition for Comparability of Actuators in the Multi-Output System

Abstract

LQ actuator selection problem for multi-output system is discussed, in which actuator sequence and input sequence are decided by minimizing quadratic control performance. This problem has combinatorial property, so it is difficult to get optimal solution. If comparability in given actuators holds combinatorial property can be dissolved. In this paper we yield sufficient condition for comparability of actuators in the multi-output system.
