Design and Implementation of Autopilot Simulator for Vehicle Control
The Lab. simulator for conducting a performance test and a reliability test on a vehicle and components has been
designed and embodied. In order to control non-linear of a vehicle, a fuzzy control algorithm, a running mode tracking algorithm and a vehicle speed control algorithm were applied to the actuator control. The vehicle controller functions were implemented; setup of the actuator, position control, the gear shift control depending upon the vehicle RPM, the serial interface function for data communication and control with the servo controller, and transmitting and receiving data. The servo controller performed the function to drive the actuator by controlling the pneumatic servo valve, and measured data information such as a position, a velocity and an acceleration as obtained through operation by means of the second differentiator and controlled a position precisely. An experimental apparatus was consisted of a dynamometer and a vehicle, and the performance and durability of the controller was verified. The Lab. simulator was mounted onto the vehicle, and the position control test and a LAP mode tracking test were conducted. It was found that the response characteristic, the tracking capability and precision of the position control were so excellent.
