Study on Guidance System Compensation Method Based on Classical Control

When air-to-air missile strikes a large maneuvering target,the increasing speed of guidance system is needed.Based on the classical control theory,the transient and frequency response can be improved by using the feedback/feed-forward control signal,the performance of the guidance loop can be further improved by introducing the actual acceleration compensation.With these methods,the guidance system compensation algorithm is designed.The performance of the guidance system compensation algorithm is simulated by linearization model,the simulation results show that the guidance system compensation algorithm can reduce the miss distance caused by target maneuvering.Finally,the angle measuring noise of the seeker is added.The performance of the guidance control system before and after the correction algorithmis simulated and compared,and the correction algorithm under the noise enviroment is optimized based on the analysis result.
