This paper presents an adaptive control strategy which combines the hierarchical control scheme with adaptive wavelet neural network for a class of multi-input multi-output (MIMO) underactuated systems with uncertain dynamics. Proposed scheme develops a systematic framework of the control components by applying hierarchical scheme to underactuated system. Wavelet neural networks are used to mimic...
The high precision of a piezo-electric positioning stage almost depends on whether the designed controller can effectively compensate the inherent hysteresis phenomenon. In this paper, an adaptive output feedback controller based on a radial basis function neural network (RBFNN) is proposed to eliminate the tracking errors caused by the hysteresis behavior. The observer-based RBFNN is used to online...
In order to implement effective control for a class of non-affine nonlinear dynamic systems, which are implicit function with respect to control input, with strong nonlinearity and uncertainty, the algorithm is established based on some mathematics theories, and the Hinfin optimal control techniques is also adopted. All of the approximation errors are weakened by a robustifying control term. Our result...
