Abstract: A novel two-degree-of-freedom(2DOF)Smith predictor control scheme for cascade time-delay process was proposed. The 2DOF Smith predictor control structure, which consist of setpoint tracking controller and disturbance rejection controller, was adopted in the main loop. And the internal model control structure was adopted in the secondary loop. The two controllers were respectively designed by an analytical method in the main loop. The setpoint tracking characteristics was decoupled from the disturbance rejection characteristics. Theoretical analysis and simulation results showed that the proposed control structure was simple, the controller parameters could be adjusted conveniently, and the system has a very good dynamic response performance and robustness.

Key words: cascade time-delay process, two degree of freedom, Smith predictor control, internal model control, robustness
