New techniques for PID controller design

This paper is introducing new categories for PID tuning methods. In this category most recent PID tuning techniques are considered entitle of PID optimal PID control signal matching group. The paper is concerned with the design of predictive PID controllers, which is an optimal PID control signal-matching method. The predictive PID controller, which has similar features to the model based predictive controller (MPC), is described. A PID type control structure is defined which includes prediction of the outputs and the recalculation of new set points using the future set point data. The optimal values of the PID gains are calculated using the values of gains calculated from an unconstrained generalised predictive control algorithm. Simulation studies demonstrate the performance of the proposed controller and the results are compared with conventional PID and generalized predictive control solutions.
