Measurement in Electric Drives

Part of the Advances in Industrial Control book series (AIC)


In a closed-loop process control system, the feedback measurement is indispensable. Voltage, current, temperature, speed, and position are the measurement of the more common variables used in the machine control applications. These variables are also used to protect the electric drive and the machine in fails situations such as locked rotor or over temperatures. In some applications, the control part should be isolated from the power stage, which is typically fed by high voltage. Then, as some of the variable measurements should be directly connected to the high-voltage side, some isolation mechanism should be used as it will be shown in this chapter. In this chapter, the design of the above measurements variables with its hardware signal conditioning, software strategies, and experimental results is deeply analyzed for the proper design of high-performance machine control.
