PID Control System Design for Automatic Tracking Laser Guided Intelligent Vehicle Based on Microcontroller
If encountering sudden obstacles or road collapses,intelligent vehicles are prone to accidents during operation.To en-sure the auxiliary driving function and safety performance of intelligent vehicles,a PID control system based on single-chip microcom-puter for automatic tracking laser guidance intelligent vehicles is designed.Install an MC9S12XS128 microcontroller processor,modify the laser,speed and angle measurement unit,intelligent vehicle PID controller,and intelligent vehicle drive module,and complete the optimization of the hardware system.With the support of the hardware system,based on the receiving results of laser signals,plan the guidance trajectory of the intelligent vehicle and complete the automatic tracking laser guidance.Utilize hardware devices to obtain the movement speed,position,and steering angle of the intelligent vehicle,and achieve the real-time detection of intelligent vehicle motion status.By taking into account the deviation between motion parameters and planned trajectory,the intelligent vehicle PID con-trol instructions are generated,and the control function of the system is achieved through the servo steering and driving speed control.Through system testing experiments,the results show that the speed and steering angle control errors of the optimized design system are reduced by 5.37 mm/s and 0.25 °,respectively,while the mobile balance of the intelligent vehicle is significantly improved.
