MATLAB Implementation of Sliding Mode Control Based on Reaching Law Approach

Implementation of reaching law-based sliding mode control in MATLAB. Sliding mode control represents an advanced control methodology that enhances system robustness and stability, particularly effective for controlling nonlinear systems. The reaching law approach serves as an optimization method within sliding mode control framework, which not only achieves control objectives but also better preserves system dynamic performance. Implementing this control strategy in MATLAB facilitates deeper understanding of its underlying principles and practical applications to real-world control problems. Key implementation aspects include defining the sliding surface using state variables, designing the reaching law to ensure finite-time convergence, and implementing discontinuous control signals with boundary layer techniques to mitigate chattering. The MATLAB implementation typically involves creating functions for system dynamics, designing controller parameters, and simulating the closed-loop system behavior using ODE solvers like ode45.
