The speed-regulation is working under d-q coordinate system of rotor, and takes rotor current component as orientation control, so there is no need to test the initial position of the rotor. 速度调节在转子d-q坐标系下进行,以转子电流矢量进行定向控制,所以无须检测转子初始位置,这样便构成了无速度传感器转子变频控制系统,提高了系统的可靠性。
It describes the working principle of CMM, derives the workpiece coordinate system of white bodywork and establishes its mathematical models. 介绍了三坐标测量系统的工作原理,并就白车身工件坐标系及数学模型的建立进行了推导。
In the typical working conditions, the static decoupling controllers of the coordinate control system can be schemed out by using the genetic algorithm. 在典型工况下,采用遗传算法辨识出协调控制对象的静态解耦网络,再分别设计压力回路和功率回路的控制器。
When working with containers, you need to worry about a third coordinate system in addition to the local and global systems. 处理容器时,除了局部和全局坐标系之外,还涉及到另一个坐标系。
In the typical working conditions, how to modeling the linear model of the coordinate control system using the genetic algorithm and the genetic programming? 分别采用遗传算法和遗传编程方法,建立典型工况下单元机组协调控制对象的线性模型。
