Brush and brushless compatible two-way servo control system

Abstract

The invention discloses a brush and brushless compatible two-way servo control system, comprising a robot movement mechanism, a two-way power MOSFET circuit, a DSP circuit and a direct current power supply. One end of the two-way power MOSFET circuit is connected with the DSP circuit, and the other end is connected with the robot movement mechanism. A servo motor current collection circuit, a protection circuit and a gate level drive circuit are arranged on the two-way power MOSFET circuit. The robot movement mechanism and the servo motor current collection circuit are in two-way connection. A QEP circuit, an SCI circuit, a PWM circuit and other interface circuits are arranged on the DSP circuit. The robot movement mechanism is connected with the QEP circuit through a coder. The servo motor current collection circuit is connected with the DSP circuit through a high-speed and high-precision AD sampling circuit. The direct current power supply is connected with a voltage division circuit. The system is brush and brushless compatible. The problem of lacking a two-way brushless motor controller and a two-way brush motor controller in the market is solved.

Description

technical field [0001] The invention relates to the technical field of servo control, in particular to a dual-channel servo control system compatible with brush and brushless. Background technique [0002] At present, the wheelchair controllers on the market mainly use brushed motor controllers, and brushless motors have the characteristics of high power density, small size, and long life. The hardware requirements are relatively high, which cannot meet the requirements of electric wheelchairs; how to combine brushed motors and brushless motors in the same servo control system to solve the current lack of dual-channel brushless motor controllers in the market, while being compatible with dual-channel motors The brush motor controller is required to better meet the market demand, which has become an important problem to be solved urgently. Contents of the invention [0003] The technical problem solved by the present invention is to provide a dual-channel servo control sys...
