摘　　要：由于飞轮储能装置要求在充、放电过程中保证母线电容电压恒定,针对传统电压外环PI控制下的非线性、鲁棒性差等问题,提出了一种改进的滑模电压平方控制,实现了系统全局线性化控制,且提升了系统在宽转速调速范围内的鲁棒性。另外将电流滑模内环的符号函数改为相对饱和的函数,在保留优良鲁棒性的基础上,减少了系统抖振与谐波效应。结果表明,所提控制策略相比传统电压控制,具有较快的响应速度与较好的抗扰能力。The requirement of the flywheel energy storage device is to ensure a constant voltage of the bus capacitor during the charging and discharging processes.Aiming at the problems of non-linearity and poor robustness under traditional voltage outer loop PI control,an improved sliding mode voltage square control is proposed.The system achieves global linearization control,and improves the robustness of the system in a wide range of speed regulation.In addition,the sign function of the current sliding mode inner loop is changed to a relatively saturated function.On the basis of retaining excellent robustness,the system chattering and harmonic effects are reduced.The results show that the proposed control strategy has a faster response speed and better anti-interference ability than traditional voltage control.
