| Summary: | 碩士 === 國立中央大學 === 資訊及電子工程研究所 === 82 === In this thesis,a new concept is suggested for a guidance system
design.By Monte-Carlo's method, a comparsion of the performance
is done among several guidance laws.In fact, the guidance
system is a time-variant system with low reaction rate. The
most advantage of the PID guidance is to explain guidance from
the control viewpoint. The feedback control system has the
advantage of reducing the sensitivity of the parameter
variation of the system and the effect of the disturbance. In
general, the modern guidance law is better than the classical
guidance law in the miss distance.From the William and Zarchan'
s paper's, the error of the estimated time-to-go degrades the
Modern guidance system(MGS) performance. During the homing
phase, the guidance system will become unstable for small time-
to-go.Basing on the control theory.it is well known that wide
bandwidth will reduce the tracking error. Our problem is how to
enlarge the bandwidth and keep the stability of the guidance
system.A two-stage compensator is used to solve this problem.
