Abstract

The invention discloses a PID (Proportion Integration Differentiation) control-based motor control system. The PID control-based motor control system comprises a keyboard, a liquid crystal display, a digital display, a single-chip microprocessor, a hall sensor, a driver, a power supply and a direct current motor, wherein the single-chip microprocessor, the driver, the direct current motor and the hall sensor are connected in sequence; the single-chip microprocessor is of 89C51; the driver is an L298N motor driving chip; the hall sensor is a 71X518 hall sensor. Since the 71X518 hall sensor is adopted to measure speed in the PID control-based motor control system, and parameters are processed by the single-chip microprocessor 89C51, the PID control-based motor control system has the advantages of high control accuracy, convenience in debugging and modifying of parameters, low cost and high applicability.

Description

technical field [0001] The invention relates to a motor control system based on PID control. Background technique [0002] In today's electrical age, electric motors have always played a very important role in modern production and life. Whether it is in industrial and agricultural production or in household appliances in daily life, various electric motors are widely used. For DC motors, the operating environment is harsh and the interference is serious. In the conventional motor speed regulation control method, the motor is unstable and has a large loss, especially at low voltage and light load, and the operating frequency is limited by the power frequency. Meet high-precision speed regulation requirements. Therefore, it is of great practical significance to study and manufacture high-performance, high-reliability DC motor control systems. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a motor control s...
