要約(英語): This paper proposes an optimal control law to suppress ripples in inter-sample of transient state of multi-rate sampled-control systems. The law is obtained by deriving equations to calculate output ripples as solutions of Lyapunov equations. So far, to reduce the ripples in transient-state, there exists only trial and error method and does not exist a systematic method. In this paper, first a reference model is defined which generates a reference output with no ripples and has the same outputs with multi-rate control systems at sampled points. Then the ripples in transient state is measured by the integrals of squared output errors. And equations to calculate the integrals are given by solving of Lyapunov equations. Finally the optimal control law is derived by differentiating the equations of several sampling intervals by the control inputs. The sampling intervals are called by horizon.
