In this paper, mathematical modeling of multi-input multi-output Quanser AERO system is obtained using Euler–Lagrange equation. Model obtained is nonlinear, and there exits cross-coupling. This nonlinearity and cross-coupling are challenging tasks for designing the controller for the Quanser AERO system. LQR controller has been widely used in literature, but it is not able to meet the desired performance specifications. To overcome this, SMC has been implemented in addition to LQR, and their performance has been compared.
