【摘要】 引入了基于频域理论的H∞回路成形方法对航空发动机进行控制器设计,有效地克服了类似于LQG的传统时域方法设计过程不透明的缺陷;为了提高控制器设计效率和准确性,在设计过程中,设计了一种能自动搜寻满足要求的权函数参数的方法,同时对传统的控制结构进行了改形,改善了控制器性能;为更充分对控制器性能进行验证,在设计的航空发动机数控系统快速原型化实时仿真平台上进行了仿真,证实了所设计的改型后的H∞回路成形控制器在航空发动机控制上所具有的良好的性能。更多还原

【Abstract】 The H∞ loop-shaping design procedure as the frequency domain approach is applied to aero-engine control system,a new method was proposed to obtain good loop-shaping weights effectively ensuring the desired performance specifications.Meanwhile,the transfigured controller was presented to improve the control qualities.Then the hardware in-the-loop simulation based on the real-time simulation platform was carried out,and the results verified that the H∞ loop-shaping methodology is suitable for aero-engine multivariable controller.更多还原
