Abstract :
The optimal self-adjusting proportional-integral-derivative regulator for the control plant with unknown parameter value is designed. The new two-step control technique is realized in this regulator. At first the main parameters with help of the special input signal are estimated. Then the coefficients of the regulator by using of the maximal stability degree condition are computed and used in the regulator. Such regulator is robust and has high control quality. The performance of the considered control structure has been examined using experimental tests. It´s the control task of the thermal control plant. The received performances have been compared to ones of the self-adjusting proportional-integral-derivative regulator E5CN of the firm OMRON (Japan).
