Fixed-Time Sliding Mode Control for a Drone Quadrotor

A fixed-time sliding mode control method is proposed in this study for a multi-input multi-output nonlinear system, a drone quadrotor. The first step consists on studying the mathematical model of the drone quadrotor. Then, fixed-time sliding mode control method is developed to control the drone quadrotor system for the purpose of solving the high nonlinearity problem, and reducing disturbances. The primary goal of this method is that the convergence time can be known. We study the system stability applying lyapunov technique to extend the control laws of the system. The capability of the proposed technique is demostrated by comparative results.
