Piezo Controller Comprises A Power Amplifier And Algorithm

Piezo controller are essential components of a piezo system. It has the function to supply the piezo actuator with the right electrical voltage. The piezo controller or piezo driver supplies the piezo with voltage and requires sufficient power capability to generate the electrical current to charge or discharge the piezo to set the voltage in appropriate times implement . Highly dynamic operation of a piezo can require high power capability. We supply electronics driver 1 - 10 amperes and 30 Amps and more for pulser electronics. The amplifiers can be operated with open or closed loop control. In closed loop mode a sensor is installed which measures the position to provide a feedback signal for the control loop. PIEZOTECHNICS offers amplifiers with analog input as standard. This allow the user to implement flexibly a control algorithm for the closed loop system using a suitable computing infrastructure. The customer can select the control law in order to optimize the system behavior such as to minimize the width of hysteresis effects, optimizing precision of the commanded displacement or optimize settling speed.
