Abstract
This paper proposes an EDM servo controller which consists of a self-tuning regulator with a proportional-integral (PI) control algorithm. In this system, an EDM gap monitor provides the feed back signal, and a high speed computer directly regulates the servo feed rate, instead of servo reference voltage, according to the stochastic characteristics of the process. The feedback signal is organized by the time ratios of gap states, and the algorithm of this control strategy is simpler, and has better control performance than many other available EDM servo adaptive control systems. Extensive experiments show that the productivity achieved by this control system is 17% higher than the model reference adaptive controller and 10% higher than the self-tuning regulator, developed earlier by the authors, and almost 50% higher than the existing control system on the machine.
