Sliding Mode Control with Exponential Reaching Law

Resource Overview

This program implements sliding mode control with exponential reaching law approach, which effectively mitigates chattering phenomenon in traditional sliding mode control through exponential convergence, making it widely applicable in high-precision systems. The implementation typically involves designing a sliding surface and implementing an exponential term in the control law calculation.

Detailed Documentation

This program demonstrates sliding mode control using the exponential reaching law method. The exponential control law improves sliding mode control performance by incorporating exponential functions to reduce control chattering, typically implemented through a term like sign(s)*exp(-k|s|) in the control algorithm. This approach has gained widespread adoption in systems requiring high-precision control, particularly in aerospace and robotics applications. The core algorithm involves calculating a sliding surface variable 's' and applying exponential decay to the reaching phase. Furthermore, depending on specific application scenarios, this control method can be further enhanced through parameter tuning or adaptive techniques to improve its performance and applicability, such as adjusting convergence rates or adding boundary layer techniques.
