Benefiting from Linear Behaviour of a Nonlinear Reset-based Element at Certain Frequencies
Nima Karbasizadeh, Ali Ahmadi Dastjerdi, Niranjan Saikumar +2
This paper addresses a phenomenon caused by resetting only one of the two states of a so-called second order "Constant in gain Lead in phase" (CgLp) element. CgLp is a recently int…

Closed-Loop Frequency Analysis of Reset Control Systems
Ali Ahmadi Dastjerdi, A. Astolfi, Niranjan Saikumar +3
This paper introduces a closed-loop frequency analysis tool for reset control systems. To begin with sufficient conditions for the existence of the steady-state response for a clos…

Complex order control for improved loop-shaping in precision positioning
Niranjan Saikumar, Duarte Valério, S. Hassan HosseinNia
This paper presents a complex order filter developed and subsequently integrated into a PID-based controller design. The nonlinear filter is designed with reset elements to have de…
