1、A very fast direct torque control for interior permanent magnet synchronous motors start upOriginal Research ArticleEnergy Conversion and ManagementSelection of the stator flux command in direct torque control (DTC) of permanent magnet synchronous motors is very important as it affects machine perfo

2、rmance. For steady state operation, it can help to decrease the stator current or machine losses. However, in order to get a fast torque response during motor start up, one needs to change both the stator flux angle and magnitude. In this paper, a method is presented to find the optimal voltage vect

3、ors to change both the flux angle and its magnitude that results in high speed dynamics for the torque response. The closed form formula given for the optimal voltage vector is derived based on maximizing the torque change in each sampling time. The simulation results show that the presented method

4、is superior to the conventional DTC. In other words, it is shown that the voltage vectors derived from the switching table for conventional DTC are not the optimal voltage vectors for the situation in which there is a step change in the torque command.Article Outline1.

6、dataReferencesA hybrid controller for the speed control of a permanent magnet synchronous motor driveOriginal Research ArticleControl Engineering PracticeThis paper introduces a hybrid controller (HC) which consists of a parallel connected sliding mode controller (SMC) and a neuro-fuzzy controller (

7、NFC) for the speed control of a permanent magnet synchronous motor (PMSM) drive. The aim of this study is to obtain a controller that eliminates the chattering phenomenon and provides a fast and smooth dynamic response for the speed control of a PMSM drive. Therefore, using an error band method, the

8、 system is controlled by the SMC to get a fast dynamic response in transient mode and is also controlled by the NFC to get a smooth dynamic response in steady state mode. To illustrate the performance of the proposed controller, the simulation and experimental studies are presented separately for th

9、e SMC, NFC and HC. The results are compared with each other and discussed in detail.Article Outline1.

27、r predictive controller (NPC) for a permanent magnet synchronous motor (PMSM) is proposed in this paper. Its objective is high performance tracking of the rotor speed trajectory while maintaining the d-axis component of the armature current at zero. The load torque and the mismatched parameters are

28、considered to be unknown perturbations. To ensure robustness against these perturbations, a disturbance observer is designed using a new gain function, and integrated into the control law. The combination of the nonlinear predictive controller and the disturbance observer works as a nonlinear contro

29、ller. The overall closed-loop system is proved to be globally asymptotically stable depending on the design parameters. The validity of the proposed controller was tested by simulations. Satisfactory results were obtained with respect to the tracking of the speed trajectory and disturbance rejection
