A technique for acceleration control with application to real-time control of a BLDC drive

Abstract

In this paper, we present a technique of acceleration control which can be used as a fast inner loop to enhance the disturbance suppression capabilities of permanent magnet brushless D.C. (PM BLDC) drives when used in typical position control applications. The proposed technique has the advantage of simplicity which should make it of considerable appeal to many practising engineers. In the paper, the technique is carefully described, and then evaluated and compared with an alternative control system design which uses standard state-feedback techniques only. The superiority of the proposed technique is demonstrated in simulation experiments, and also in a real-time implementation for position control using a PM BLDC drive. © 1992.
