This paper studies the consensus tracking control for a class of uncertain high-order nonlinear multi-agent systems under an undirected leader-following architecture. A novel distributed finite-time adaptive framework is proposed based on barrier function. The cascaded high-gain observers are introduced to solve problem robust with unmeasured intermediate states in framework. schemes guarantee ...

An indirect adaptive consensus control method is presented for multi-agent systems (MASs) with unknown hysteresis states and input. All system that can be utilized to design the controller are measured by sensors subjected hysteresis, thus, state values inaccurate. Meanwhile, it difficult compensate input coupled hysteresis. The function from agent’s neighbors also increases difficulty of desig...

This paper studies the semi-global tracking consensus problem for general multi-agent networks with input saturation and periodic intermittent communication. The considered is solved by proposing an efficient distributed observer-based control protocol, where inputs of follower agents are subjected to saturation. First, a low-gain feedback method introduced suppress constraint, output protocol ...

one of the main problems in wind energy conversion system (wecs) is how to achieve maxim­u­m output power in different wind speeds. maximum methods for maximum power point tracking in wind energy conversion syst­e­ms require the knowledge of system characteristics and mechanic sensors. so, using these methods practically will follow with high price and an abundant difficulties. in this paper, n...
