Control system for a small electrodynamic exciter

The paper focuses on development of a control system for an electrodynamic exciter used in vibration testing. There is described one of the possible ways to generate sine sweep and random testing signals based on filtering the control value with an inverse filter created from frequency response of an exciter. The system is designed to be universal, that wide range of components within control loop, as piezoelectric accelerometers and electrodynamic shakers, can be utilized.
