| Abstract |
In this paper an H-inf controller is designed for three phase asynchronous motors. The model of the motor was given in its state space representation in the d-q reference. A feedback controller was used which was synthesized by combining a full information controller with an estimator to reach the desired results. A simplified model was used in the design process increasing the modelling noise of the system. There are exogenous inputs considered as disturbances, which are not correlated with the measurement noise. With the designed controller the effects of the disturbances entering the plant and the influence of the measurement noise and modelling errors can be minimized. The desired controller is given by a state space model. The simulation of the system was made with MATLAB/Simulink. The controller is realized as a Simulink embedded S-function, allowing good reference tracking. |
