| Abstract: | The rotor speed and electromagnetic torque estimation with good performance of induction motor based on the algorithm of estimating induction motor′s dynamic velocity and equation of electromagnetic torque by the compensation method was realized. It resolved the real time problem by the discontinuity torque and speed estimation method. In order to reduce the cost of monitoring and measuring system of induction motor, high performance andlow cost single-chip computer,12-bit serial analog-to-digital converter, general purpose voltage and current sensors were used without the specialized speed and torque sensors in the hardware design of the monitoring and measuring system.The result of simulation and experiment showed the validity of the estimation on the rotor speed and torque. |
