MC9S12DG128单片机在柴油机电子调速系统中的应用

Application of MC9S12DG128 MCU in Electronic Control System of Diesel Engine

提出了一种基于16位单片机MC9S12DG128的柴油机数字式电子调速系统,通过单片机对柴油机转速进行PID调节,克服了传统机械式调速系统的诸多缺点。试验结果表明:该控制系统能有效地提高柴油机调速系统的响应速度,改善数字式电子调速系统的动态性能。

This paper proposed a digital electronic control system based on the 16-bit single chip MC9S12DG128 for a diesel engine, which realizes the PID adjustment of the rotational speed of a diesel engine by the MCU. Experimental results show the control system can effectively improve the response speed of the engine when compared with the traditional mechanical adjusting system.
