Design of Deadbeat Control Systems Considering the Maximum Error Bound

Abstract

This paper deals with a design of SISO, linear time-invariant, discrete-time deadbeat control systems. Based on the l¹-optimal control theory and the 2-DOF compensation scheme, we propose a design method for the deadbeat control systems which minimize the maximum error bound of outputs to a fixed reference input and persistent bounded disturbances. Using the proposed method, one can design compensators taking account of a trade-off between the maximum error bonud and the settling time. A numerical example is given to illustrate the validity of the method.
