农用机械LPG发动机控制系统的抗干扰设计

Design for Anti-disturbance Technology in Control System of Agriculture Machine LPG Engine

对农用机械LPG发动机的电子控制系统进行抗干扰的研究与应用,以确保控制系统的工作稳定性和可靠性。同时,分析了干扰的不同种类、形式及其来源,并阐述了农用机械发动机控制系统的主要干扰原因。其采取了减少干扰源、减少干扰从输入输出通道进入等措施,对抑制干扰起到决定作用,能够有效防止干扰,保证控制系统工作正常。

The technology about anti -disturbance was researched and applied in order to ensure the stability and relia- bility in electronic control system of agriculture machine LPG engine. The disturbance sort and form was analyzed, the main disturbance was illustrated in control system of agriculture machine engine. Reducing disturbance source in I/O channel was the key role to restrain the disturbance and ensure control system operation safely.
