To simplify the control of their autonomous underwater vehicle, Juan Rojas and Nathan Liebrecht of the Autonomous Robotic Vehicle Project at the University of Alberta join Connell D'Souza of MathWorks® to talk about using MATLAB® to design, simulate, and implement a Linear-Quadratic Regulator (LQR) controller for their vehicle.
Juan and Nathan start by explaining, at a high level, the theory behind an LQR Controller. LQR Controllers are based on optimal control theory which
Juan and Nathan then demonstrate their workflow for designing this system. They use MATLAB and the Symbolic Math Toolbox™ to symbolically solve the system equations and linearize them. The
