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 introduced reset-based nonlinear element, bound to circumvent the well-known linear control limitation - the waterbed effect. The ideal behaviour of such a filter in the frequency domain is unity gain while providing a phase lead for a broad range of frequencies, which clearly violates the linear Bode's gain phase…

Fractional-Order Single State Reset Element

It is shown in this paper that using the proposed reset element architecture, CgLp gets closer to its ideal behaviour for a range of frequencies, and its performance will be improved accordingly.

Band-Passing Nonlinearity in Reset Elements

This paper investigates the higher-order harmonics for reset elements with one resetting state and proposes an architecture and a method of design which allows for band-passing the nonlinearity and its effects, namely, higher- order harmonics and phase advantage.

A Frequency-Domain Tuning Method for a Class of Reset Control Systems

Based on the loop-shaping approach, the recent frequency-domain framework and the frequency- domains stability method are utilized to provide a reliable frequency- domain tuning method for CgLp compensators and the results show that this method is effective, and the tuned C gLp can achieve more favorable dynamic performance than the PID controller.

Frequency-Domain Modelling of Reset Control Systems using an Impulsive Description

A novel approach for modelling RC is considered, which uses state-dependent impulse inputs and is shown to permit an accurate computation of closed-loop RC behaviour starting from an open-loop model, thus linking both aspects, enhancing system understanding.
