摘要:
在Buckboost电路拓扑结构和工作原理分析的基础上,引入虚拟开关量构建Buckboost电路连续导电模式和断续导电模式的合并状态方程,在合并状态方程基础上采用等效控制法推导Buckboost变换器的PWM滑模变结构控制方程,将指数趋近率应用于控制方程,并将等效控制变量作为PWM控制的占空比,得到基于指数趋近率的PWM滑模变结构控制方法。仿真实验和实测验证结果表明:Buckboost变换器的PWM滑模变结构控制方法能使Buckboost变换器快速达到稳定状态,具有较好的动态特性和鲁棒性。
Abstract:
Based on the topological structure and working principle of the buckboost circuit,the combined state equation of buckboost circuit continuous current mode and discontinuous current mode was constructed using virtual switching value,and a PWM sliding mode variable structure control equation of the buckboost converter was then derived using the equivalent control method.An exponential approach law was applied to this control equation,and the equivalent control variable used as the duty cycle of PWM control to obtain a PWM sliding mode variable structure control method based on exponential approach law.The experimental results show that the proposed control enables the system to reach the steady state quickly and proposes good dynamics and robustness.
