Abstract
In this work the required components and assemblies were developed. In addition a prototype was built. With it, it should be possible to measure and run piezoelectric transducers up to a capacity of 120 nF. Furthermore ICP-sensor-inputs are provided, because especially acceleration sensors are often used in applications of active vibration cancelling. In this solution, the piezoelectric ceramics get measured by special charge amplifiers and driven by power amplifiers, which are able to power piezo actuators within a bandwidth of 10 Hz to 4 kHz with a voltage up to 150 V.
The signals get filtered by software-adjustable analog filters and processed by a single board computer with an XPC-Target-realtime-kernel from Mathworks. In this configuration complex control-loops made in Matlab-Simulink can be run. The following picture shows the prototype.
