Summary SLIDING MODE CONTROL SHORT NOTES
This document provides short notes on Sliding Mode Control (SMC). It outlines the controller's advantages, such as robustness and ease of implementation , and its main drawback, chattering. The notes use phase plane diagrams to explain the intuition behind SMC , describing how it constrains a system's behavior to a "sliding surface". It discusses how this constraint makes the system robust to disturbances. The document details the problem of chattering and explains how to mitigate it by defining a "boundary layer" and using methods like a saturation function. It also includes the mathematical derivation for the SMC control law and various reaching laws.
