    摘 要:針對降壓 (Buck) 變換器運行過程中所產(chǎn)生的混沌現(xiàn)象,根據(jù)變換器的工作特性確立其數(shù)學(xué)模型,并分析其通往混沌的道路。分別使用了兩種控制策略使系統(tǒng)穩(wěn)定于周期 1 狀態(tài):第一種是設(shè)計非線性控制器,施加該控制器后,系統(tǒng)的動態(tài)響應(yīng)快,抗擾性強,但輸出電壓與參考值有一定的偏差;第二種是基于終端滑模自抗擾控制 (TSMADRC) 的雙閉環(huán)控制策略,使用該控制策略后,系統(tǒng)輸出超調(diào)量小、動態(tài)響應(yīng)快且具有較好的暫態(tài)響應(yīng),并且從源頭上避免了混沌現(xiàn)象的發(fā)生。仿真結(jié)果表明,兩種控制方法均可以抑制混沌現(xiàn)象的發(fā)生,使 Buck 變換器工作于穩(wěn)定的周期 1 狀態(tài)。

    Abstract: The chaos phenomenon occurs during the operation of the Buck converter, so the paper, according to the working characteristics of the converter, builds a mathematical model to analyze its pathway to chaos. Then, two control strategies are applied to stabilize the system in the period 1.The first is designing a nonlinear controller which makes the system have fast dynamic response and strong disturbance rejection, but the output voltage is deviated from the reference value. The second is a double-loop control strategy based on Terminal Sliding Mode Auto Disturbance Rejection Control (TSMADRC). It not only makes the system have small output overshoot, fast dynamic response and good transient response, but also avoids the chaos phenomenon from the source. The simulation results show that both control strategies are able to curb the chaos phenomenon to make the Buck converter work stably in the period 1.
    Key words: Buck converter; chaos phenomenon; nonlinear controller; terminal sliding mode auto disturbance rejection control
