Research on Vector Control of Permanent Magnet Synchronous Motor of High precision turntable Based on Fuzzy Neural Network

High precision turntable control systems have high requirements for motor control performance. This paper provides a vector control scheme of permanent magnet synchronous motor (PMSM) based on fuzzy neural network. With fuzzy neural network controller (FNNC) as the current regulator, a fuzzy controller is introduced in the speed loop, and its output is used as the current loop limit to achieve the purpose of speed limit. Simulation and experimental results show that for the complex situation of turntable operation, the method has good torque tracking and motor speed limit performance.
