— In this paper, we introduce variable gain controllers for linear motion systems designed to improve transient performance. In particular, we focus on the well-known tradeoff induced by integral action, which removes steady-state errors due to constant external disturbances, but deteriorates transient performance in terms of increased overshoot. We propose(More)
— In this paper, we employ an extremum-seeking control strategy for steady-state performance optimization of variable-gain controllers for linear motion systems. Variable-gain control can balance the tradeoff between low-frequency disturbance suppression and sensitivity to high-frequency noise in a more desirable manner than linear controllers can. However(More)
— In this paper, we introduce piecewise affine variable-gain controllers as a means to improve performance compared to linear controllers. Variable-gain controllers can improve upon the tradeoff between low-frequency tracking and sensitivity to high-frequency disturbances. However, performance-based tuning of the variable-gain controllers, is far from(More)
— In this paper, we experimentally demonstrate an extremum-seeking control strategy for nonlinear systems with periodic steady-state outputs, for the adaptive design of variable-gain controllers. Variable-gain control can balance the tradeoff between low-frequency disturbance suppression and sensitivity to high-frequency noise in a more desirable manner(More)
— In this paper, we introduce the split-path nonlinear integrator (SPANI) as a novel nonlinear filter designed to improve the transient performance of linear systems in terms of overshoot. In particular, this nonlinear controller targets the well-known trade-off induced by integral action, which removes steady-state errors due to constant external(More)
