Resumo
The project consists in developing an algorithm in the MATLAB® environment to find the best tuning for a PI speed controller using the Simulated Annealing Method. An independently excited DC motor with an inner armature current control loop with another PI controller was used and modelled in the SIMULINK® environment. In order to keep the system linear, the gains of the PI current controller are adjusted so that, for the rated armature current reference, the armature voltage applied to the motor does not exceed its rated value. The speed control was realized in an outer control loop with the gains limited so that, for a specific speed demand, the armature current reference does not exceed its rated value. A nonlinear model was considered where a saturator block was placed at the exit of the PI speed controller to limit the armature current reference to the PI current controller.
