Research on Infrared Sensor and Tracking-Control Algorithm of the Model Car

Abstract

Based on 51 microcontroller, according to the detection results of the intelligent model car running state through the infrared sensors, this paper uses the pulse-width-modulation speed modulation and incremental PID algorithm to control motor speed and to achieve the purpose of rapid and accurate tracking. The motor control system model of the intelligent model car is established, and the parameters are set for the incremental PID control strategy based on Matlab. The simulation results show that the system can get good control effect through the setting parameter under the condition of different paths.
