Pre-estimating Dynamically the Optimum of Extremum Value Control System with Large Time Delay Element Based on Correlation Identification
As to the optimum of extremum value controlled plant,if the transfer function G(s) of its linear part is only with the high order dynamic elements,the optimum of extremum value control system could be dynamically pre-estimated by using the method based on correlation identification we presented,the pre-estimating method has the estimate speed quickly,anti-jamming ability strong,accurate,highly effective and so on the merits.However,if the controlled plant is simultaneously with high order dynamic elements and a large time delay element,the method could not be used directly to pre-estimate dynamically the optimum of the extremum value control system.A new improved pre-estimating method is presented so as to resolve the problem above.After we have in detail analyzed the derivation process of the pre-estimating method we presented,Fully taking into account the effects of large time-delay element,a number of conditions have been improved,the algorithm based on correlation identification has been extended,the optimum of extremum value control system with a large time delay element is well resolved by the extended algorithm.
