Model predictive control is a kind of control method based on parameter model. However, in the actual system, the parameters of the motor may deviate from the parameters in the model due to the influence of various objective factors, leading to deterioration of the control performance. In this paper, a strong parameters robustness model predictive current control (MPCC) method for permanent-magnet...
In the paper, the non-sensor control method of the sliding mode observer (SMO) was proposed and used for estimating the rotor position and speed of the Switched Reluctance Motor (SRM). Based on linear inductance model of SRM, the motor position and speed of the SRM was estimated by the phase voltage and current. With the soft of Matlab-Simulink, a simulation model with the SMO for the SRM was built...
This paper presents a compensation method of matrix converter drive system in case of commutation voltage error and unbalanced input voltage with disturbance observer. There are two compensation disturbances. One is commutation voltage error. This is caused by the dead-time between the turn-on and turn-off of the IGBT mode switches. The other is unbalanced input voltage. As the matrix converter has...
This work considers the seldomly treated case of rotor turn-to-turn fault of a doubly-fed induction generator. This fault can take place where the doubly-fed induction generator is a standard solution in wind power stations. For investigations an error-adoptable three phase machine model is derived and simulated. Furthermore the model is integrated in a wind energy plant model and simulated for a...
