A new gain-scheduling sliding mode controller for permanent magnet synchronous motor (PMSM) was designed to achieve position tracing control and robust control. The sliding mode position controller is designed to ensure the tracing and robust performance of the PMSM servo system firstly, and then the gain-scheduling based on fuzzy logic theory is adopted to reduce chattering of sliding mode controller...
Based on backstepping sliding mode control and adaptive techniques, a novel robust adaptive control scheme is proposed for BTT missiles with unmatched uncertainties. Continuous sliding mode control with one adaptive gain parameter is used at each step of backstepping design to deal with the uncertainties. "Explosion of terms" is solved by adaptively estimating the upper bound of the derivative...
The paper studies the robust control of non-minimum phase nonlinear system based on the differential geometry theory. The nonlinear system could be expressed as input-output dynamics with the unstable internal modes, through nonlinear coordinate transformation. Virtual controller is introduced to stabilize zero dynamic, and the sliding mode controller, which is robust to the parameter perturbations...
The problem of the reliable control for a class of uncertain switched delay systems containing actuator failures is addressed in this paper. The upper bounds of uncertainties are assumed to be unknown. When actuators suffer "serious failure"-the never failed actuators can not stabilize the given system, based on multiple-Lyapunov function method, the adaptive feedback controllers being able...
