摘　　要：为解决气体轴承或磁悬浮轴承独立作为高速电主轴支承时存在的不足,将静压气体轴承和主动磁悬浮轴承结合形成可控性好的气磁悬浮混合轴承,构建了气磁轴承支承的新型高速电主轴系统并提出了协同控制,仿真分析与试验结果表明:协同控制下,气磁轴承支承高速电主轴的响应速度快,抗干扰能力强,具有良好的稳态特性和动态特性,控制效果优于PID控制。In order to solve the shortcomings of high-speed motorized spindle supported independently by gas bearing or magnetic suspension bearing,the aerostatic bearing and active magnetic suspension bearing are combined to form a gas-magnetic suspension hybrid bearing with good controllability.A new high-speed motorized spindle system supported by gas-magnetic bearing is constructed and the cooperative control is proposed.The simulation analysis and test results show that:under cooperative control,the high-speed motorized spindle supported by gas-magnetic bearing has fast response speed,strong anti-interference ability,good steady-state characteristics and dynamic characteristics,and the control effect is better than PID control.
