ZG tracking control of 3-input 3-output nonlinear system with GD used additionally once more

In this paper, the tracking control problem of a 3-input 3-output nonlinear system is investigated and solved. By adopting and generalizing Zhang-gradient (ZG) method, as the novel combination of Zhang dynamics (ZD) and gradient dynamics (GD), in a quite different way (i.e., with GD used additionally once more), a ZG controller group is designed and proposed for the tracking control of the aforementioned system. Furthermore, simulation results substantiate the efficacy of the proposed controller group in fulfilling the tracking control task of the 3-input 3-output (3I3O) system.
