摘要:
An alternative minimum variance self-tuning controller is presented. The proposed controller, which is designed to combine a minimum variance strategy with a Dahlin controller, overcomes the shortcomings of the original version of minimum variance control and is found to be competitive with the generalized minimum variance controller. It tracks set-point changes with the desired speed of response, penalizes the excessive control action, and can be applied to non-minimum phase systems. The control algorithm is also extended to multi-variable systems. Robust pole-assignment can be incorporated to enable closed-loop system stability characteristics to be readily specified. Simulated results are presented to indicate the advantages of the proposed controller.
