Power-Law Compensator Design for Plants with Uncertainties: Experimental Verification

A power-law compensator scheme for achieving robust frequency compensation in control systems including plants with an uncertain pole, is introduced this work. This achieved through appropriate selection of the parameters, which guarantee that Nyquist diagram open-loop system compensator-plant crosses a fixed point independent plant pole variations. The implementation fractional-order performed utilization curve-fitting-based technique and derived rational integer-order transfer function realized on Field-Programmable Analog Array device. experimental results confirm phase margin well preserved, even ±40% variation location plant.
