AN ADAPTIVE POLE-SHIFTING ALGORITHM AND ITS IMPLEMENTATION FOR REFERENCE TRACKING OF A DC DRIVE USING A DSP CHIP

A strategy for the design of a single-input and single-output self-tun ing controller for reference-signal tracking is described in this pape r. An existing algorithm for shifting the closed-loop poles radially t owards the origin in the z-domain for regulation has been utilized for reference-signal tracking, by combining it with a well-known control law. The use of a self-searching pole-shifting technique increases the flexibility of the strategy when applied to varying operating conditi ons encountered in various industrial applications. A self-tuning cont roller has been implemented using a single-chip digital signal process or (DSP). The result is a reduction of system hardware, cost and calcu lation time.
