This paper presents the design and construction of an inverse controller for the compensation of hysteretic actuator characteristics. The approach is based on the so-called modified Prandtl-Ishlinskii method. The field-programmable-gate-array-based hardware solution allows hysteresis-free actuator operation at signal frequencies up to 1 kHz. Finally, the effect of hysteresis compensation is presented for an example involving a magnetostrictive actuator.
