FPGA-Based Compensator of Hysteretic Actuator Nonlinearities for Highly Dynamic Applications
IEEE/ASME transactions on mechatronics
A method developed at the Laboratory of Process Automation (LPA), Saarland University, for compensating complex hysteretic actuator and sensor characteristics in open loop control is based on the so-called modified Prandtl-Ishlinskii method. Within the scope of the EU-funded project MESEMA (contract AST3-CT-2003-502915) the algorithm for the inverse filter was implemented in a FPGA and a digital circuit was developed, which can compensate two hysteretic actuator characteristics independentlydoi:10.1109/tmech.2007.915065 fatcat:34ufdiukwvhnxdmgetmdlsd6ve
