Based on actor-critic neural networks (NNs), an optimal controller is proposed for solving the constrained control problem of affine nonlinear discrete-time system with disturbances. The actor NNs provide signals and critic work as performance indicators controller. By converting original state constraints into new input constraints, penalty functions are introduced cost function, then transformed unconstrained one. Further, relationship between worst-case disturbance obtained using Game...
ABSTRACT Variable wheelbase wheeled mobile robot (VW‐WMR) is capable of maneuvering flexibly and traversing on rough soil terrains within confined spaces. While the steering radius model can be robustly changed by variable length, a challenge posed in accurately tracking predefined trajectory through alteration length. A dynamic curvature (DSC) control method proposed this work to overcome challenge, which achieved two different approaches utilizing length manipulating drifting motions....
Abstract A novel event‐triggered heuristic dynamic programming (HDP) algorithm is proposed for the near‐optimal control of uncertain discrete‐time nonlinear input‐affine systems. Based on input‐to‐state stability (ISS) analysis, a new mechanism (ETM) designed. Under constant coefficients, Lipschitz‐like assumption that forms basis event‐triggering condition considered to be conservative. To further reduce conservativeness triggering and enlarge average interevent time, an adaptive threshold...
