A novel data fusion based on McDE-PF (particle filter integrated with memetic compact differential evolution) is proposed for aviation positioning and navigation application by fusing BDS/GPS positioning data. McDE-PF is used as the local filter to process the measurements from the GNSS receivers. the flight test practical data is used to validate the effectiveness of the fusion method, Comparative simulation and experiment studies confirm the validity of the presented method.

this paper addresses the function projective synchronization control for a class of neutral complex dynamic network with nonlinear coupling strength and unknown time-varying parameters. An adaptive controller is designed for neutral complex network with time-varying coupling strength. In addition, a sufficient condition is given to guarantee the function projective synchronization of complex dynamic networks. the simulation example demonstrates the proposed method.

this article develops a novel data-driven policy iteration (PI) to obtain nearly optimal control of nonlinear systems with asymmetric input constraints. the data-driven PI is derived from an early established model-based PI. Owing to the datadriven PI sharing the same solution as the model-based PI, the convergence of the data-driven PI algorithm is guaranteed. the implementation of the newly developed data-driven PI algorithm relies on an actor-critic structure consisting of two kinds of neural networks (NNs). Specifically, the critic NN aims at estimating the value function and the actor NNs aim at approximating the control policies. the weight parameters used in the critic and actor NNs are determined via the least squares method together withthe Monte Carlo integration technique. Finally, a nonlinear plant is provided to validate the proposed data-driven PI algorithm.

this paper presents a robust adaptive repetitive control(RARC) method for trajectory tracking of uncertain robotic manipulators. Repetitive control is applied for periodic trajectory tracking and a sigma modification is introduced in the periodic learning laws to guarantee the robustness of the system. All the signals in the closed loop are proved to be bounded. An open-loop learning algorithm with switching s modification is designed to achieve asymptotic convergence of the tracking errors when the disturbances disappear. the simulation is made to show the effectiveness of the algorithms.

In this work, a new indirect iterative learningcontrol (ILC) method with an iterative dynamical identification of the set-point command is proposed. the ILC law of the set-point is derived from the dynamical linearization of a nonlinear ideal ILC law. then, the estimation law of the parameter in the ILC law is derived from the optimization of a cost function. At last, simulations demonstrate the advantages of the proposed scheme.

this paper, an adaptive fuzzy controller is proposed to a class of discrete-time nonlinear systems with strict feedback. In these systems, total disturbance consists the fuzzy approximation error and unknown external disturbance. And the proposed accurate disturbance observer could track the approximation disturbance accuratly. It can be proved via the Lyapunov theorem that all signals in this closed-loop system are guaranteed to be bounded. Finally, the simulation example demonstrates the effectiveness of the proposed scheme.

To address the failure of precise overload tracking and anti-interference caused by the difficulty of accurate modeling of a complex aircraft, the controller designing method based on deep reinforcement learning is studied. this paper trained the control network based on the Proximal Policy Optimization (PPO), studied the tracking control problem of the aircraft, and accurately tracked the typical command signals. Fixed-point simulation of the aircraft is performed, with results showing that, in presence of aircraft model parameter variation and external disturbance, the controller based on deep reinforcement learning can achieve accurate tracking of overload commands.

this paper addresses the problem of prescribed performance control for nonlinear discrete-time systems such that the tracking error is constrained to a predesigned region all the time. Moreover, a new second order sliding mode control method together with an novel transformed error strategy is proposed to guarantee the prescribed convergence rate and steady state error behavior to a predefined region all the time. Further, the designed controller depends only on the input/output data, which is more effective in the complex industrial processes. the potential of the results is illustrated on the simulation example.

Modeling and control design of complex chemical processes are challenge tasks because of their multi-variable, time-delay and non-linear features. On the other hand, the plant dynamics are hard to characterize precisely on line when facing uncertain disturbance. In the light of this, this paper presents a data-driven backstepping control scheme for the nonlinear chemical process. Compared with other regular chemical process control schemes, the proposed scheme is independent of specific mathematical models, and free of decoupling operation, linearization, or off-line recognition and modeling. By constructing Lyapunov function and feedback control rate based on real-time data, the integral stability is guaranteed. Williams-Otto reactor example is provided to demonstrate the effectiveness and applicability of the scheme.
