Backstepping Control of Speed Sensorless Permanent Magnet Synchronous Motor
摘要
Abstract
A control of permanent magnet synchronous motor by the estimated rotor speed using a new reduced-order Luenberger observer is proposed.The motor speed is acquired through observer constructed with stator q-axis current and speed equations.The observer is simple and can achieve fast convergence through eigenvalues placement.Backstepping control is used to design system controllers and the system can achieve fast speed tracking and torqure response.Matlab simulation and experimental result is applied to proves the efficiency and feasibility of system design.关键词
