Abstract

Against such characteristics as large delay, nonlinear, time-varying and uncertainty of controlled object, the P-LADRC cascade control system is proposed in this paper. The principle of the LADRC is briefly introduced firstly, and then QPSO algorithm is applied to tune the initial parameters of LADRC-P controller thus achieving better performance of the main steam temperature. In addition, control effect of the new structure and PID cascade control structure is compared. Results show that when using different control strategies for the same load, performance under P-LADRC control is better than that under PID control.
