中文说明:使用字段的变频调速控制面向感应电机控制......从三个物理定子和转子绕组出发,几个状态空间动态模型的感应电机介绍在这一章了。每个模型 clarifies 特定的动态属性。确定并分析了其稳态运行矿泉水: 当恒定振幅与频率的正弦波电压应用时,特别是计算稳态转矩-转速特性曲线。这条曲线揭示了许多重要的非线性特征: 例如,对于一个给定的负载扭矩可能有两个工况稳定,另一个不稳定 ;他们变得越来越近,随着负载转矩增大负载转矩分岔价值最高。更一般地,显式计算动态逆系统: 它产生的电压输入,需要跟踪所需的时间不同转子速度形与所需的转子予以充分弹性模量。予以充分弹性模量进行参数化处理控制输入: 尽量减少功率损耗,或为了保持电压 m,它可能被选择。


English Description:

Field oriented variable frequency speed control for induction motor control... Starting from three physical stator and rotor windings, several state space dynamic models of induction motor are introduced in this chapter. Clari? Es specific dynamic attributes for each model. When the sine wave voltage with constant amplitude and frequency is applied, especially the steady-state torque speed characteristic curve is calculated. This curve reveals many important nonlinear characteristics: for example, for a given load torque, there may be two stable conditions and the other unstable; they become closer and closer, and the bifurcation value of load torque is the highest as the load torque increases. More generally, the dynamic inverse system is explicitly calculated: the voltage input generated by it needs to track the required time, different rotor speed shapes and the required rotor elastic modulus. The control input is parameterized with sufficient elastic modulus: to minimize power loss, or to maintain voltage m, it may be selected.
