【Abstract】 In the high performance vector control,measurement and control system of the asynchronous machine,in order to obtain the operating state of machine,thoroughly research control scheme of asynchronous machine,it needs to acquire,save and display parameters such as torque and rotor speed of electrical machine.The measurement of torque and rotational speed of asynchronous machine,especially the measurement of torque,is normally realized by machinery sensors,generally the result is gotten by inverting the torque to variation of physical parameters.By analysising the torque and rotate speed measure principle of the machine,this paper designed a new measure system that can get the torque and rotational speed of asynchronous machine by measuring the basic parameters of the machine based on software technique.It shows experimentally that the system has high accuracy and good anti-jamming ability,and the operation is simple.This method makes the measurement equipment more reliable and durable.It can reduce the cost of the measurement equipment.更多还原
