Discrete Sliding Mode Control Based on Equivalent Control

Sliding mode control represents a widely adopted control methodology applied across diverse fields, particularly in aerospace engineering. Although some implementations exist for sliding mode control, the discrete sliding mode control (2) approach based on equivalent control remains relatively scarce in available programming solutions. It is important to highlight that sliding mode control offers significant advantages including strong robustness against system perturbations, adaptability to model uncertainties and nonlinear systems, and straightforward implementation. These characteristics make it particularly valuable in engineering applications. Key implementation aspects typically involve designing a sliding surface using equivalent control theory, discrete-time system modeling, and chattering reduction techniques through boundary layer methods. This revision aims to better communicate these technical advantages and implementation considerations for international technical audiences.
