| Abstract: | The working environment of electronic control unit (ECU) is quite poor, and more uncertain facts exist, which seriously affect the normal function of control system for electronically controlled engines. Based on the condition of control system, several disturbance modes are analyzed. A lot of design principles are put forward. Using the restrain technology, we discuss the anti-disturbance techniques of space field, supply power system, process channel and software. One anti-disturbance watch dog circuit is designed, which improves the reliability and stability of control system. |
