Feedback chopper control of series motor on the regenerative braking mode

Abstract

Through the method of point transformation of Poincare-Andronov, the pulsewidth control of torque with natural sampling on the leading edge of the pulses for a series motor, on the regenerative braking mode, is studied. The main purpose of this paper is to obtain a recurrent model that allows the analysis of the closed loop performance of this non-linear system, as well as comparison with the model obtained for the same system in the traction mode. In both modes, non-linear implicit recurrent models of first order are obtained for the case of proportional controller.
