Design of Predictive Control Systems based on Pole Assignment

A new design method is proposed for digital controllers based on a discrete convolution model and closed-loop pole assignment. The discrete convolution (impulse response) model is used to predict future values of the output from current and past inputs. The controller parameters can then be calculated in a straightforward manner so as to place the closed-loop poles at desired locations. The effects of modeling errors and the choice of pole locations are analyzed. Simulation results are included to illustrate the advantages of the new approach.
