摘要
舞台演出过程中,平台经常需要快速起停,故其运行的平稳性和定位的准确性将直接影响着安全与使用。传统舞台运动采用三段式速度控制模型,但是采用这样的速度给定,舞台变化剧烈,演员在舞台上不安全,对机械传动系统会造成有害的冲击,影响整个设备的使用寿命。针对上述问题,给出了舞台七段式速度控制模型,探讨了不同阶段的控制策略,并在SEW变频器舞台控制系统中得到实现。
When performance is going on,quick start and stop of platform are needed,so their stability of move and accuracy of orientation will directly affect the safety and application. At present,a speed control mode of three phase is mostly applied on stage. But if we use this mode,there will be a bad impact on moving system which will influence the safety of actor and worklife of the equipments because of a sudden speed of platform. Aiming at this problem,this paper proposed a speed control mode of seven phase. It also discussed control strategies at different moments. And it has been implemented in stage system of SEW inverter control.
