The presence of strong disturbances usually causes great control performance degradation of outlet temperature in process furnace with the properties of time delay and inverse response. This article mainly focuses on lumped disturbance rejection of the processes with inverse response and time delay by disturbance observer-based (DOB) enhanced composite cascade control scheme. The disturbances considered...
As a main steam temperature control system features characteristics such as large time-delays, time-varying parameters, and nonlinearity, it is difficult to obtain accurate results using traditional proportional-integral-derivative (PID) control. As a result, a predictive functional-PID cascade control algorithm is proposed. In the cascade control system designed by the proposed algorithm, a conventional...
In this paper, the finite-time tracking problem is investigated for a permanent magnet synchronous motor (PMSM) and a continuous finite-time controller is designed. The whole tracking error system is considered as a cascaded system. Two continuous finite-time stabilizing controllers are designed for two subsystems respectively. Then finite-time stability results for cascaded systems are employed to...
