摘要: 保證系統(tǒng)魯棒穩(wěn)定,同時滿足系統(tǒng)性能指標要求始終是控制設(shè)計的目標。該文根據(jù)轉(zhuǎn)臺測角系統(tǒng)對激磁電源穩(wěn)定性和性能指標的要求,提出了采用H優(yōu)化控制理論,以魯棒穩(wěn)定為基礎(chǔ)的閉環(huán)激磁電源幅值回路設(shè)計的方法,討論了H控制器的求解過程。經(jīng)四個轉(zhuǎn)臺長期使用驗證該設(shè)計方法的有效性和合理性,完全滿足了高精度轉(zhuǎn)臺的需要。

Abstract: It is always the goal of the control systems design that ensuring the system robust stability and satisfying the requirements of the system performance specifications at the same time. In this paper, based on the requirements of stability and performance specifications of the excitation power supply for the angular measurement system of test turntable, a design method, is presented, in which the robust stability based H-optimal control theory is applied to the magnitude loop of excitation power supply with closed-loop control. The solving process of the H controller is discussed. Long period of operation of the four test turntables has proven that the validity and rationality of the design method fully satisfy the requirements of high precision test turntable. -
