Dynamic Relative Gain Array Method of Flight Control System
摘要
Abstract
A method of analyzing dynamic relative gain array (DRGA) for multiple inputs multiple outputs (MIMO) flight control system is proposed. Both the time-based dynamic relative gain array and frequency-based dynamic relative gain array are calculated for the linear model of aircraft. According to the time-based DRGA, the correlation degree between plant inputs and outputs can be obtained. The correlation degree is about the entire working time, not just the final steady-state point. According to the frequency-based DRGA of working frequency range, the inputs and outputs can be rationally matched, so the flight control system of appropriate frequency characteristics can be analyzed and designed expediently. Case studies show that the same pairing results can be obtained from the two methods, the combination of time-based and frequency-based methods can lead to comprehensive analyzed results.关键词
