In order to weaken the adverse effect of backlash nonlinearity on dual-motor driving servo system, an adaptive control strategy was proposed. The state-space model of the system was first given. By introducing the virtual control quantity, using backstepping approach and recursively selecting the Lyapunov function, and adopting a radial-basis-function (RBF) neural network to design adaptive law, a state feedback-based RBF neural network backstepping adaptive controller was designed, and its stability was analyzed. Compared with the conventional PID control in simulation results, the proposed control strategy shows better position tracking performance and higher robustness.

Taking the IRB460 robot as the research object, This paper builds an industrial robot virtual workstation for automatic sorting and palletizing in one-in-two-out mode simulated by the RobotStudio software. The conveyor chain transports the packaged materials to its end, and a Cognex camera is installed at the end to detect the color and position information of the packaged materials. Then the robot grabs the material according to the feedback information from the camera. It stacks the red materials to the left side on the pallet, the green materials to the right side on the pallet.

With the continuous promotion of digitalization and the intelligent transformation of the electric power industry, various data information has exploded. There is a practical requirement for power system operators to have accurate and timely access to relevant data. Data visualization technology provides a solution for the decision-makers in the electric power industry to quickly discover the intrinsic correlation of data, intuitively grasp the trend of data changes, and deeply explore the value hidden behind the data. This paper develops power system data visualization methods through web language technologies: the html, css, JavaScript, Echarts, Flask framework and Ajax technology. The ultimate goal is to dynamically monitor data changes in the power system and to visually reveal the nature of power operations.

In this paper, a neural network sliding mode control based on neural network disturbance observer is proposed for the control of MEMS gyroscopes under external disturbances. In the design process, two sets of RBF neural networks are incorporated in the sliding mode controller design as well as the disturbance design separately to release the dependence of each module on gyroscope system parameters. Meanwhile, the integration of the neural disturbance observer can help to alleviate chattering phenomenon in conventional sliding mode control forces. Simulation studies are implemented to verify the effectiveness of the proposed control scheme.

Piezoelectric stick-slip actuators have influences such as model uncertainty, nonlinear factors and external disturbances that reduce control accuracy. In this paper, an integral terminal sliding mode controller is proposed for the precise positioning control of piezoelectric stick-slip actuators. The method can achieve convergence in finite time and serve to reduce the jitter steady-state error. The convergence law using a combination of power convergence law and exponential convergence law can reach the sliding mode surface at a faster rate. The stability of the control method is verified by the Lyapunov method. Finally, the effectiveness of the modified control method is verified by simulation. The results show that the control method improves the dynamic performance and stability accuracy of the system more than the traditional sliding mode controller.

The wind and solar radiation of each location show distinct local features. This paper proposes a spinning reserve setting method that considers the local wind and solar radiation features. Through the statistics of local historical wind speed and solar radiation data, the wind and solar radiation transition matrices are established. Using the transition matrices, the power system's additional spinning reserves to compensate for wind and solar power fluctuations are set. The spinning reserves are then applied to the unit commitment calculations. A case study is performed on a 10-units system using the proposed method.

An anti-saturation fault-tolerant control method based on adaptive dynamic programming (ADP) was presented for the reconfigurable manipulator with uncertain environment. Differential homeomorphism theory is used to change the system structure of nonlinear transformation, and convert nonlinearly of sensor faults of the system. The adaptive fault observer is designed to real-time detection of actuator and sensor faults, and the fault sensor signal is replaced by the output signal. The hyperbolic tangent function is used to solve the actuator saturation problem. Then, an evaluation neural network (NN) is established, and the Hamilton-Jacobi-Bellman (HJB) equation is solved by online strategy iterative algorithm, then the value of approximate optimal feedback controller can be obtained. Using Lyapunov stability theorem to assure the uniformly and ultimately bounded (UUB) of the nonlinear system. Finally, the validity of the presented optimal FTC scheme is confirmed by simulation results.
