This book systematically presents the fundamental theories, methodologies, and application techniques of sliding mode variable structure control from a MATLAB simulation perspective. It synthesizes the author's years of teaching and research experience in control systems while incorporating recent advancements from both domestic and international peers. The 10-chapter coverage includes sliding mode control development overview, continuous/discrete-time system implementations, fuzzy/neural network integrations, backstepping-based design, dynamic sliding mode control, disturbance estimation techniques, Terminal sliding mode control, and several novel approaches - all validated through MATLAB simulation code implementations with detailed algorithmic explanations.

Mie scattering is the most fundamental and widely-used algorithm for particle scattering calculations, offering unparalleled accuracy when dealing with particle scattering at wavelength scales. Interestingly, Mie scattering isn't an independent theory but rather an analytical solution of Maxwell's equations for spherical media. Due to the complexity of the solution process, Gustav Mie's pioneering complete solution became classical and was named Mie Theory. Key technical implementation involves coding the complex mathematical formulations using MATLAB, which significantly reduces computational time and improves accuracy through numerical optimization techniques.
