Analysis of Turbo-Shaft Engine Control System Dynamic Performance with Parameter Limitations

Effect of limitations of aero-engine parameters was studied.The purpose of the analysis was to achieve better dynamic performance.Limitation rules that may be adopted in turbo-shaft engine control system were presented and a digital controller with multiple limitation loops was designed.Simulation results show that different limitations of parameters bring different effects on engine dynamic performance.Selecting limitations of parameters reasonably can optimize engine dynamic performance.
