A computer study of a PID automatic voltage regulator part II: digital PID voltage regulator with dynamically varying weighting parameters
The influence of a digital PID voltage regulator on the transient performance of a synchronous machine is examined through a simulation study. The simulation model is described in Part I and the pertinent control algorithm is described in this paper. A dynamic variation of the weighting coefficients of the voltage regulator according to the variances of the manipulated output signals has been investigated. Simulation studies conducted on a micro-machine generating unit model under different types of system disturbance conditions show that the transient response of a generating unit having a digital PID regulator with dynamically changing weighting coefficients is superior to that of the same unit when equipped with a conventional continuous acting regulator.
