“…Especially in the case of external disturbances acting on time-delay systems, an input-time-delay even degrades the disturbance rejection capability, for a certain degree of different phases between the input control and the disturbances. To improve the disturbance rejection performance in input-time-delay systems, many methods, such as repetitive control (RC) (Inoue et al, 1981a; Pérez-Arancibia et al, 2010; Yamamoto and Hara, 1988), disturbance observer (DOB) (Musmade and Patre, 2015; Natori and Ohnishi, 2008; Shim et al, 2008) and robust control (Hua et al, 2007; Kwon and Park, 2004; Wang et al, 2013) have been proposed. The extended state observer (ESO) is a typical method in active disturbance rejection control (ADRC), which is used for measuring the total disturbance in delay-free systems.…”

An innovative approach combining equivalent-input-disturbance (EID) theory with the internal model principle is applied to achieve periodic disturbance rejection in input-time-delay systems. The EID estimator, which exhibits the synthetic effect of the time-delay and the periodic disturbance as an input-dependent disturbance, is constructed by inserting appropriate time-delay elements to compensate for the total influence of the input-time-delay and the periodic disturbance. A sufficient stability criterion is derived based on the separation theorem and the small-gain theorem. A design algorithm is developed for the system based on the stability criterion. Design and simulation results for the example are also employed to compare our method with the disturbance observer approach, and to demonstrate the validity of our method.

SUMMARYThis paper proposes a consensus protocol for a class of high-order multiagent systems under directed networks. It is supposed that each agent is exposed to an external disturbance additive to its control input. Based on the H 1 optimization theory, the consensus protocol gains are designed in order to attenuate the effects of the external disturbances on the performance of the multiagent system. The main problem of existing H 1 high-order consensus protocols in the literature is the dependency of the design on the information of coupling matrices associated with networks topologies. Despite existing H 1 high-order consensus protocols in the literature, the proposed consensus protocol can be designed in a fully decentralized manner based on no global information. The main idea of the design is to propose an H 1 control formulation in which the coupling information of the agents is considered as exogenous signals, while the coupling effects of these signals lead to achieving consensus in the multiagent system. Numerical examples verify the effectiveness of the proposed consensus protocol.
