基于无源性的同步电动机自适应控制
Adaptive Passivity-Based Control of Synchronous Motors
摘要
Abstract
Due to the potential value in applications and theory, nonlinear control strategies of synchronous motors, especially passivity-based control(PBC) methods, have been a focus in the literature. The main purpose of this paper is to develop a control algorithm that forces the synchronous motor to track flux and speed trajectories with time-varying load torque. To achieve this, an adaptive PBC method is developed. The key point with this method is the identification of terms, known as workless forces, which appear in the dynamic equations of synchronous motor but do not have any effect on the energy balance equation of the closed loop. PBC combined with adaptive control scheme not only reserves the advantages of PBC such as nonexistence of singularity, but also represses the flux and speed tracking error caused by rotor resistance variation. This leads to a simple control structure and enhances the robustness of the control system. The reasonability and validity are testified by the experimental results based on dSPACE.关键词
