In this paper, a stable adaptive PI control strategy based on the improved just-in-time learning (IJITL) technique is proposed for permanent magnet synchronous motor (PMSM) drive. Firstly, the traditional JITL technique is improved. The new IJITL technique has less computational burden and is more suitable for online identification of the PMSM drive system(More)
The purpose of this paper is to present an adaptive method for improving the control performance of permanent magnetic synchronous motor (PMSM) in operating condition. The approach allows to reduce speed tracking error and to cope with external disturbance. The methodology of speed control is presented in detail and two controllers are tested, traditional(More)
To enhance the control performance of permanent magnet synchronous motors (PMSMs), a generalized predictive control (GPC)-based proportional integral feedforward (PIF) controller is proposed for the speed control system. In this new approach, firstly, based on the online identification of controlled model parameters, a simplified GPC law supplies the PIF(More)
As few or no failures occur during life test and accelerated life test for long-lifetime products, FR-4 printed circuit boards (PCBs) are employed as research objects to conduct performance degradation test under high temperature and humidity. Based on the analysis of the failure mode, failure mechanism and the study on the degradation parameters of PCB,(More)
Three-phase current is very important in the vector control scheme of permanent magnet synchronous motor, and its sampling precision affects the servo control performance directly. In the low-cost servo system, to simplify the structure and reduce the volume, three-phase current is often not accurately detected because the current sensors are usually(More)
Position control is a typical application of linear servo system. In this paper, to reduce the system overshoot, an integral plus proportional (IP) controller is used in the position control implementation. To further improve the control performance, a gain-tuning IP controller based on a generalized predictive control (GPC) law is proposed. Firstly, to(More)
