Multivariable ripple-free deadbeat control

Abstract

The design of multivariable ripple-free deadbeat controllers is a complex task. One approach which has shown promise for solving multivariable ripple-free deadbeat control (MRFDC) problems is the use of Diophantine equation parameters. The problem of solving robust multivariable ripple free deadbeat with time delays has not been solved. This paper proposes a hybrid two degree of freedom controller utilizing the parameterization of Diophantine equation to build a multivariable ripple-free deadbeat control (MRFDC). The important feature of the proposed approach is that it combines the concept of multivariable input with robust ripple-free deadbeat control. Simulation results show that the output signal tracks the input sinusoidal signal in short settling time.
