摘要
Abstract
In the design of air-defense missile control system,how to quickly and efficiently design the control system to meet the given index has always been a hot issue.In this paper,the control structure is designed from the mathematical point of view.Taking the design of the rolling channel control system as an example,the mapping relationship between the time-domain index,the frequency-domain index and the control parameters,and the mapping relationship between the time-domain index and the frequency-domain index are established by using the analytical method,the root locus method and the amplitude-phase characteristic Bode diagram method.The mapping relationship can give consideration to both time-domain and frequency-domain indexes to design control parameters more quickly and efficiently,and can also obtain the rule of index changes when control parameters change.Finally,the correlation among system time constant,rise time,cut-off frequency and closed loop bandwidth is established analytically.Through this correlation,a clearer physical understanding of the system can be established,which is helpful to guide how to take measures when the system oscillates or diverges in engineering design.关键词
