Sliding mode control method for networked control system under circumstance of uncertain probability of occurrence

The invention provides a sliding mode control method for a networked control system under the circumstance of an uncertain probability of occurrence. The sliding mode control method belongs to the technical field of sliding mode control. The sliding mode control method comprises the steps of: firstly, designing a sliding mode function for a dynamic model of the networked control system having distributed sensor delay and bounded time-varying delay under the circumstance of data packet loss with an uncertain probability of occurrence, constructing a controller of the system and substituting thecontrolling into the dynamic model and the sliding mode function, ensuring that the obtained sliding mode function converges into a belt-like neighborhood of a sliding mode surface within a finite time, and acquiring equivalent control at the moment; substituting the equivalent control into the networked control system to obtain a closed-loop system, analyzing the stability of the closed-loop system, and finally acquirin
