The fundamental concepts of servo motion control have not changed significantly in the last 50 years. The basic reasons for using servo systems in contrast to open loop systems include the need to ...

Feedforward control represents an essential strategy in modern motion systems, where anticipated disturbances and system dynamics are counteracted by pre-calculated control inputs. This proactive ...

Abstract: Magnetic hysteresis in the core of actuators at various air gaps limits the use of high-precision applications and motion systems. The Gap-dependent Prandtl-Ishlinskii hysteresis model is ...

Abstract: Differential flatness has been defined in the literature for continuous time dynamical systems and for discrete time systems. We define flatness of automata from the perspective of ...
