In this paper, a class of a class linear singular system with an arbitrary initial state was proposed based on singular value decomposition. A novel generalized theoretical result is presented by using the D-type learning law. We established the convergence conditions of algorithm. By the matrix theory, we give rigorous convergence proof. the effectiveness of the theoretical result is illustrated in two application examples.

this technical note addresses an adaptive iterative learningcontrol (AILC) problem for nonlinear dynamical systems with partially unknown iteration-varying parameter. Referring to the scheme of state-space, an AILC effort is presented for randomly varying reference tracking together with initial shift problem in iteration domain. Furthermore, the AILC technique is extended to systems with several parameters in discussion. A simulation example confirms the validity of the proposed method.

this paper presents a PID-type ILC (iterative learningcontrol) algorithms for system which undertaken performance tasks repetitively over a pre-specified finite-time interval in the presence of initial state error, and the convergence analysis shows that the tracking error converges to zero asymptotically as time goes to infinity. Furthermore, a kind of initial rectifying strategy is addressed to eliminate the effect of the fixed initial state error, and the limit trajectory is stated. At last, numerical results are addressed to demonstrate the validity of the proposed learningcontrol algorithms.

the note considers an iterative learningcontrol scheme for a kind of switched repetitive systems. the manipulated systems are specified by arbitrary switching signals with respective to both time variable and iteration index. By employing Lebesgue- p norm, the learning performance is analyzed and a sufficient condition of convergence is derived. Results show that the concerned control law works well for tracking problem of the switched systems when the switching rules are expanded to time-iteration domain. Simulation is included to verify the validity of the approach.

In this paper, we propose an output feedback tracking control scheme for a class of continuous-time nonlinear systems without specific model. A radial basis function neural network (RBFNN) observer is designed to online estimate the unmeasured inner state variables only using the input and output data. Based on the designed RBFNN observer, a sliding mode controller is derived to guarantee that the system states follow the desired trajectories. Simulation results on an example show the effectiveness and tracking performance of the proposed scheme.

the problem of model free adaptive control algorithm for a class of nonlinear systems with output saturation constraints is considered in this paper. Based on the compact form dynamic linearization data model, a modified model free adaptive control algorithm using saturated system output is constructed. A sufficient condition for guaranteeing the stability of the modified algorithm is given and the convergence of the tracking error is proved. It is shown that the model free adaptive control using saturation output can also guarantee the convergence of the tracking error. the theoretical results are validated by a numerical example.

this paper deals withthe problem of sampled-datacontrol for T-S fuzzy systems with quantized signals. Based on the constructed Lyapunov-Krasovskii functional(LKF), Jensen's inequality and Free weight matrix, some sufficient conditions are obtained in the form of linear matrix inequalities(LMIs). By combining the input delay approach and dynamic quantizer, the sampled-datacontroller is designed to guarantee that T-S fuzzy systems with quantized signals is asymptotically stable. Finally, a numerical example is presented to verify the feasibility and effectiveness of the proposed methods.

the paper solves the problem of decentralized robust adaptive output-feedback control for a class of large-scale stochastic time-delay nonlinear systems. Simulation results show that the closed-loop system is globally stable in probability and the output signals can converge to a small neighborhood of the origin in probability under some milder conditions.
