...Yerui Fan; Yaxiong Wu; Jianbo Yuan Purpose This study aims to improve the muscle model control performance of a tendon-driven musculoskeletal system (TDMS) to overcome disadvantages such as multisegmentation and strong coupling. An adaptive network controller (ANC) with a disturbance observer...

...Nigar Ahmed; Mou Chen Purpose The aim of this research paper is to design a disturbance observer (DO)-based robust adaptive tracking control of uncertain nonlinear system subject to unknown nonlinear disturbance. Design/methodology/approach To achieve desired control objectives, i.e. nonlinear...

...Rong Mei Purpose This paper aims to study the issue of the three-dimensional formation coordinated control for the unmanned autonomous helicopter (UAH) by using the sliding mode disturbance observer. Under the designed formation coordinated controller, the desired formation can be maintained...

...Qing Wang; Changyin Sun; Xiaofeng Chai; Yao Yu Purpose This paper aims to develop sliding mode control (SMC) methods for second-order multi-agent systems (MAS) in the presence of mismatched uncertainties. Design/methodology/approach Based on the disturbance observer (DOB), discontinuous...
