摘要
结合某型航空用活塞式发动机节气门自动控制问题,建立了节气门系统数学模型;通过系统分析给出了自适应脉动PID控制算法,在系统数字仿真基础上确定控制器的参数;通过发动机实验,实现了节气门的较为精确控制。实验结果表明,与传统PID控制算法相比,自适应脉动PID控制在小阶跃信号输入下响应时间提高了10%以上,稳态误差减小了16%以上。
We first established the mathematic model of the throttle valve of a certain type of aeronautic piston engine. Then, an Adaptive Pulse PID （APPID） is designed based on system analysis. Parameters of the designed controller are confirmed based on the system digital simulation. Experimental results show that the designed control- ler can achieve more exact position control for the throttle valve. The APPID is superior to the conventional PID with 10% percent increase in response time and 16% percent decrease in steady state errors.
