BLDCM Fuzzy Sliding Mode Control Based on Network Control System

摘要：

A design proposal of BLDCM remote closed loop control system is proposed. There is a central controller and a networked control interface in the system. The central controller realizing the motor speed control remotely, is composed of TMS320F2812 DSP and Ethernet controller RTL8019AS. The embedded Ethernet control interface includes C8051F020 MCU and Ethernet microcontroller CP2200. The dual-closed loop control method is used in the control system. A simplified Fuzzy Sliding Mode Control (FSMC) strategy is used in the outer speed control loop to enhance the real-time ability of BLDCM remote control system. The FSMC strategy is performed by the central controller. PI controller is adopted in the inner loop current regulator, carried out by Ethernet control interface. The Ethernet control interface drives motor operation, runs real-time data acquisition of the operation condition, then transmits parameters to the main controller via Ethernet It can change brushless dc motors operating mode according to the instructions which the central controller sends out Simulation results show that FSMC strategy applied in the speed controller can obviously reduce the effect of the network time-delay, and improve the system dynamic performance and robustness.
