Against such characteristics as large delay, nonlinear, time-varying and uncertainty of controlled object, the Smith-LADRC cascade control system is proposed in this paper. The principle of the LADRC is briefly introduced firstly, and then the LADRC-P control system with Smith predictor is designed and the closed loop system is studied in MATLAB simulation. In addition, control effect of the new structure and Smith-P cascade control structure is compared, and the robust performance is analyzed as well. Results show that when using different control strategies for the same load, performance under Smith-LADRC control is better than that under Smith-P control. The new control structure shows excellent control performance, outstanding adaptability and robustness against model uncertainties and external disturbances.
