A Double Power Reaching Law of Sliding Mode Control Based on Neural Network

Abstract EN

For discrete system, the reaching law election and controller design are two crucial and important problems.

In this paper, an improved double power reaching law of SMC and a controller combined with neural network have been investigated.

Theory proves that this method can eliminate the chattering and increase the reaching rate.

Furthermore, when there is a certain external interference, the regulating function of neural network can ensure strong robustness of the system.

Simulation results show that compared with exponential reaching law, single power reaching law, and traditional double power reaching law, the proposed reaching law has faster convergence speed and better dynamic performance.
