ELECTRONIC CONTROL FOR FUEL SUPPLY OF DIESEL ENGINE ON THE BASIS OF PROGRAMMABLE PID-REGULATOR

The article presents a schematic diagram of the Euro-3 diesel engine electronic control and describes hard- and software platform of the high pressure fuel pump pneumatic actuator control that allows to realize the concept of electronic fuel supply control of diesel engine KamAZ-740. The strategic dependence beetwen the angular position of fuel pump governor lever and the angular position of electronic accelerator pedal were put on the basis of electronic control concept. Implementation of this dependence was carried out by applying a modulated PWM signal with determined duty cycle by the controller to the coil proportional solenoid valve, which is responsible for the amount of air pressure in the working chamber of the power air cylinder, connected by articulated-type to the governor lever of the high pressure fuel pump. In this case, the feedback control by position of governor lever of the high pressure fuel pump was introduced in the control circuit, but engine crankshaft speed control was carried out using a software continuous PID governor. Developed strategy gives possibility to track the deflection  of control parameter from a predetermined value by real-time and almost instantly, to make a control action on actuators to eliminate this deflection, while providing a minimum time of transition. Governor’s setting (proportional, integral and differential component) performed empirically using the classical Ziegler – Nichols method, based on the analysis of the safety factor of automatic control system. The results of calculating the coefficients of proportional integral-differential regulator and oscillograms HIL experiment on testing the proposed diesel engine throttle control strategies using visualization CoDeSys V2.3 are given in activity.
