摘要：针对BUCK变换器的复杂性和时变性,提出了采用通用控制器和滑模-通用控制器的控制策略。应用状态空间平均建模法,建立电流连续型(CCM)Buck变换器的仿射非线性模型。利用RBF神经网络和积分器组成动态神经网络结构逼近BUCK变换器的逆模型并由此组成CMC控制器。设计了滑模-通用控制器,进一步改善了系统的鲁棒性。在Matlab/Simulink下进行了系统建模和仿真研究,结果表明该方法在输入电压和负载电阻变化时,能有效减小系统状态误差和提高系统稳定性。
A slide mode control--common model control（SMC--CMC） controller was proposed to deal with the time-- variable and complexity of the switching mode power converters. Using the state space average modeling method, a nonlinear model of BUCK converter working on current conduction mode （CCM） was set up. Dynamic neural network which was constructed based on a number of integrators and RBF neural network was employed to approximate the inverse model of the dynamic system. Using this inverse model to build a CMC controller. The introduction of slide mode control was to improve the robustness of controller. The modeling and simulation of system was implemented under Matlab/Simulink. The result of simulation confirms show that the SMC--CMC control schemes are capable of reduced steady state error and improve controller＇s reliability during supply change and load variations.
