摘要:
为了保持离散指数趋近律法设计的全局滑模控制系统的良好瞬态特性,削弱全局滑模控制系统的抖振,简化离散全局滑模控制律结构和设计,提出了一种结构更简单的离散全局衰减律。理论分析了离散全局衰减律下准全局滑动模态的收敛性和稳态特性,给出了全局衰减控制律的设计方法。仿真研究了离散全局衰减律用于离散全局滑模控制Buck变换器设计的正确性和有效性。仿真结果表明,全局衰减律适用于离散全局滑模控制,削弱了系统抖振。离散全局衰减控制Buck变换器较离散指数趋近控制具有更小输出电压纹波。
Abstract:
For reserving the excellent dynamic characteristic of GSMC(global sliding mode control) with the discrete exponent reaching law,while weakening the chattering of GSMC system,and simplifying the structure and design of discrete global sliding mode control law,the simpler discrete global attenuation law method of discrete GSMC was proposed.The theoretical analysis of convergence and stability of quasi global sliding mode with the discrete global attenuation law was given,and then the design method of global attenuation control law was shown.The validity and feasibility for application of the discrete global attenuation in discrete GSMC Buck converter design were studied by simulation.Simulations show that the global attenuation law is suitable to design the discrete GSMC,and weakens the chattering of GSMC system.The output voltage ripple of Buck converter with discrete global attenuation control is smaller magnitude than one with discrete exponent reaching control.
