In this paper, a novel proportional-integral (PI) switching surface is introduced for determining the synchronization performance of systems in the sliding mode motion. Based on the sliding mode controller, the system is established by a robust control scheme which guarantees the occurrence of a sliding motion of error states even when the parameter uncertainty and external disturbance are present...
In this paper, robust output-feedback stabilization is presented for a class of uncertain stochastic nonlinear systems with time-varying time delays. First, the conditions of existence and uniqueness of the solution process are provided and two new stability notions are introduced for stochastic time-delay systems. Based on these preparations, for a class of uncertain stochastic nonlinear systems...
The requirements for humanoid robot joint controller include small size, low dissipation, high control precision and response speed. Aimed at these requirements, a new control strategy that combines fuzzy PD control with single neuron self-adapting PID control is proposed. Experiments show that this control strategy could improve response speed, control precision and robustness.
