Abstract:

In order to meet the control performance requirements of ETCS(Electronic Throttle Control System), such as fast computational performance, low-cost, miniaturization, FPGA(Field Programmable Gate Array) is adopted as the hardware implementation of controller and integral separation is added to mature PI
D(Proportional, Integral, Differential) control algorithm. And the integral separation PID controller with Catapult C highlevel synthesis tools is implemented based on FPGA full hardware solution. An integral separation PID controller on a FPGA chip is designed for ETCS. In addition, AD/DA acquisition board is designed to implement the data transmission between integral separation PID controller based on FPGA and electronic throttle. Finally, tracking experiments of electronic throttle are performed and the results demonstrate the effectiveness of the designed integral separation PID controller based on FPGA.
