Abstract

A functional feature of the application of electronics used for the automatic control of internal combustion engines is necessity in the proportional conversion of ECU electrical signals into the mechanical processes based on corresponding elements motion.For such conversion of information actuating mechanisms are used, referred as actuators. Actuators in the form of electrical machines (stepper or precision electric motors) or electric apparatuses (electromagnets and solenoids) are the mostly widespread in ICE. As a physical object of the research, the unit of Heinzmann, model StG 6-02V that is based on a DC electric drive controlled by a pulse-width modulation signal, was selected in the current work. It has a toothed gearbox and a non-contact reverse positional connection. This actuator pro-vides an output torque of 6 Nm and 36-degree range of output shaft rotational angle. The functional scheme of the electronic system of automatic control of a diesel engine based on mentioned device is developed. The PIDregulator with feedback is used to control the actuator. A design formula that can be incorporated in the controller algorithm to calculate the integral component of the PID regulator was also obtained. Values of empirical coefficients were determined in this formula. The results of experimental confirmation of the correctness of the approach taken are presented. Thus, the new formula for determining the integral component of the PID regulator differs positively from the well-known solutions because the new approach is free from storing the whole array of previous data with discrepancy in the controller’s RAM, that simplifies the application of the developed algorithm greatly and speeds up the computational capability of the controller.
