摘要
建立了发动机节气门伺服系统的非线性模型,并进行了线性化处理,得到了简单有效的控制模型;以波波夫超稳定性理论为基础,设计了伺服系统的自适应控制律;通过计算机仿真验证,在保证伺服系统响应速度的同时,自适应控制算法有效地提高了伺服系统的控制精度和稳定性;采用微控制器进行了机载实验,实际超调量仅为0.1%,跟踪控制误差小于0.1°。
A nonlinear model of the servo control system of an engine throttle was presented,which was linearized for a well-performed control system design.Based the Popov hyper stability theory,an adaptive rule of throttle valve servo control was proposed.By computer simulation,the adaptive control effectively improved the control precision and robustness of the engine throttle valve in addition to quick response.Experiments on the engine through a micro-controller show that its overshoot is only 0.1% and its tracking error is 0.1°.
