摘要
采用非线性控制方法———能量成型和端口受控哈密顿(PCH)系统理论,研究了Cuk变换器的控制问题。建立了Cuk变换器的PCH数学模型,利用互联和阻尼配置的能量成型方法,给出Cuk变换器的反馈镇定原理,分析了平衡点的稳定性,从而实现了Cuk变换器的控制。仿真分析表明,所设计的控制器具有较快的响应速度和较好的动态性能,具有很好的应用意义。
A novel nonlinear control method-energy-shaping and port-controlled Hamiltonian (PCH) systems method is applied to control Cuk converter. From the average models of Cuk converters, the PCH mathematical model of Cuk converter is established. Based on the energy-shaping method of interconnection and damping assignment, the feedback stabilization theory of Cuk converter is given. The equilibrium stability of the system is also verified. The simulation shows that the control system has good dynamic performances and practical prospects.
