Finite-Set Model Predictive Current Control of Induction Motors by Direct Use of Total Disturbance

چکیده
Disturbance rejection strategies are very useful for the robustness improvement of predictive control method. But they can only be used in modulated-based methods such as continuous set model (CS-MPC) and deadbeat control. This paper presents a robust current prediction based on total disturbance observer (TDO), which is applicable finite (FS-MPCC). In proposed method, directly part instead loop. So, method has two advantages over rejection-based CS-MPC schemes. The first advantage no need controller, an essential CS-MPC. Therefore, simpler fewer parameters. second feature that stationary frame. this way, frame transformation avoided model. Moreover, to guarantee zero steady-state error model, proposes complete designing process TDO convergence analysis. performance system evaluated through simulations experimental tests.

Model predictive control (MPC) based methods are gaining more and more attention in power converters and electrical drives. Nevertheless, high computational burden of MPC is an obstacle for its application, especially when the prediction horizon increases extends. At the same time, increasing the prediction horizon leads to a superior response. In this paper, a long horizon MPC is proposed to c...

In this paper, we present a novel model predictive control (MPC) scheme that incorporates stability information derived from a control Lyapunov function (CLF) to dynamically prune suboptimal sequences from the search space and decrease the computational burden placed on the controller. The CLF used for pruning is then incorporated into a cost function that penalizes energy in the error system a...
