چکیده

this paper deals with leader-following and leaderless consensus problems of high-order multi-input/multi-output (mimo) multi-agent systems with unknown nonlinear dynamics in the presence of uncertain external disturbances. the agents may have different dynamics and communicate together under a directed graph. a distributed adaptive method is designed for both cases. the structures of the controllers simplify their implementation and reduce computational cost. unknown nonlinearities are estimated by a radial basis function neural network (rbfnn). the ultimate boundness of the closed-loop system is guaranteed through lyapunov stability analysis by introducing a suitably driven adaptive rule. finally, the simulation results verify performance of the proposed control method.

Dynamic Sliding Mode Control of Nonlinear Systems Using Neural Networks

Dynamic sliding mode control (DSMC) of nonlinear systems using neural networks is proposed. In DSMC the chattering is removed due to the integrator which is placed before the input control signal of the plant. However, in DSMC the augmented system is one dimension bigger than the actual system i.e. the states number of augmented system is more than the actual system and then to control of such ...
