Relay Microprocessor System for Controlling the Fuel Feed in the Diesel

The relay control is known to permit the design of the control systems invariant with respect to outer disturbances. The features of the offered method include the relay control for each state variable and the changing value of the output signal of the relay element. To improve the electronic controller of the diesel rotation frequency a number of variants for developing the scheme structure of controlling the fuel feed in the diesel with high pressure pump are considered on the basis of digital model. In introducing feedbacks of all state variables the structures realized by means of analog (proportional) and ralay controllers were compared.
