摘要
针对传统升压电路升压能力不足的缺陷,提出一种新型耦合电感高增益直流变换器(Fibonacci switch capacitor-Y sources DC-DC converter,FSCYS)。采用动态响应性能和鲁棒性能优越的滑模变结构控制,实现了优于PID控制的直流闭环滑模控制器设计。利用Matlab/Simulink软件仿真及实验对比了两种控制方式在输入电压和负载扰动下的动态性能。仿真和实验表明:滑模变结构控制以其简单的建模方式、超快的动态响应和较强的鲁棒性等特点适合高阶直流变换器的闭环控制。
Aiming at the deficiency in boost capacity of the traditional booster circuit,a new type of coupledinductance high-gain DC-DC converter(Fibonacci switch capacitor-Y sources DC-DC converter,FSCYS)was proposed. Using sliding mode variable structure control with superior dynamic response performance and robust performance,the design of a DC closed-loop sliding mode controller superior to PID control was realized. The dynamic performance of two control methods of input voltage and load disturbance was compared by Matlab/Simulink software simulation and experiment. Simulations and experiments show that the sliding mode variable structure control is suitable for closed-loop control of high-order DC-DC converters due to its simple modeling method,ultra-fast dynamic response and strong robustness.
