大功率包装机械起动优化控制研究

A Research of Optimum Start Control about a Large Packing Machine

提出了对大功率包装机械的时间控制、转速控制及电流控制三原则，实现了该类电动机起动过程的优化控制。实践表明，新的控制方案能明显减小起动过程中电机的发热，延长电机的使用寿命。

of having big inertia and require big start torque, a large packing machine is usually driven by a wounded rotor asynchronous motor.In this paper an optimization starting control system was introducde to the reader. A control strategy, a framework of hardware, was introduced in detail.An integrated control theory composed of time, speed and current were put forward. All about these new ideas and new measures have been proven to be correct and practicable.
