【摘要】：本文針對傳統(tǒng)PI控制器存在的不足,利用fal函數(shù)和傳統(tǒng)的PI控制器級聯(lián)構(gòu)造了非線性PI控制器,并通過對fal函數(shù)的特點進行理論與仿真分析,揭示了不同參數(shù)對非線性函數(shù)的影響。然后將設計的非線性PI控制器應用于DC-DC變換器的控制環(huán)節(jié)中,與傳統(tǒng)的PI控制進行對比,本文以DC-DC變換器中的Boost變換器為例,對提出的非線性PI控制器進行研究,仿真和實驗結(jié)果表明,基于fal函數(shù)的非線性PI控制器和較傳統(tǒng)的PI控制器相比能夠克服調(diào)節(jié)時間與超調(diào)之間的矛盾,可以更快速,更平穩(wěn)地實現(xiàn)系統(tǒng)的動態(tài)調(diào)節(jié)。
[Abstract]:Aiming at the deficiency of traditional Pi controller, the nonlinear Pi controller is constructed by using fal function and traditional Pi controller cascade, and the characteristics of fal function are analyzed by theory and simulation. The influence of different parameters on nonlinear function is revealed. Then, the designed nonlinear Pi controller is applied to the control link of DC-DC converter and compared with the traditional Pi control. In this paper, the boost converter in DC-DC converter is taken as an example to study the proposed nonlinear Pi controller. The simulation and experimental results show that the nonlinear Pi controller based on fal function can overcome the contradiction between adjusting time and overshoot compared with the traditional Pi controller, and can realize the dynamic adjustment of the system more smoothly and more smoothly.
