abstract: In this paper, a new approach to predictive control for speed control of a permanent magnet synchronous motor fed by a matrix converter is presented. The principle of this approach is to extend the possibilities of control by offering additional virtual vectors and to find the vector which minimizes the cost function. This process includes two main steps: first one will determine the location of vector in space vector and the second one will calculate the module of this voltage vector. In detail, a discrete mathematic model of drive system is built to predict the behaviors in the next step under a set of finite control states (FCS). This set will include not only eight real voltage vector from a three-phase two-level matrix converter but also the virtual voltage vectors. Predictive controller optimizes a predefined cost function in order to find a voltage vector giving the best result. Space vector modulation (SVM) technique will be used to generate the found voltage vector. The whole system has been modeled and simulated by using MATLAB and SIMULINK software to verify the performance of proposed method under different load and speed conditions. Results also are compared with classic direct predictive control about fundamental value and total harmonic distortion (THD) to highlight the improvement.
