Time Suboptimal Pole Assignment Control via Relative Degree Reduction

This paper builds on the previous results achieved in designing pole assignment controllers for the lst and the 2nd order systems with constrained control signal. By examining properties of the control loop with the reduced relative degree of the original plant, it prepares methodology for applying the achieved results for controlling higher order systems with constained input. The success of the relative degree reduction by introduction of a fictive output that involves derivatives of the original output is shown to be dependent on the anticipation of the working range of the controlled system.
