| Summary: | Sliding Mode Controller (SMC) is applied to models of two electric motors, i.e. direct current and induction motors. SMC is chosen as the system's controller due to its insensitivity to parameter changes and disturbance when the system is in sliding condition. This implies that the system's stability is guaranteed and there is no need to have a precision model. The performance of the controller is highly dependent on the chosen S constant (sliding surface). In this thesis, the S constant is obtained by solving LMI (Linear Matrix Inequalities) which may be solved by a convex optimization algorithm. LMI parameters that influence the value of S are λ, and cost function's weighting matrices (Q and R matrices). The design method is adopted from other researcher that is been published. The simulation results so that the system's performance is good in term of speed response and the ability to compensate the changes of motor parameters and load. This may be seen from its small error steady state. |
