Existing real-time data processing will come to a performance limitation with the rapid development of power grid. This paper proposes a method of distributed storing and processing for real-time data in smart grid dispatching and control systems. The method applies the multi-machine-multi-thread and parallel computing technology to improve data processing efficiency. Real-time data is partitioned...
This paper presents the background and related researches of the intelligent control theory, introduces the related research about fuzzy control theory and neural network. By exploiting the characteristics fuzzy control and neural network, and combining them to make the control decision, we proposed a novel intelligent control system for a sensor network. The system can predict the sensors' states...
Active Reflector is one of the innovations of Five-hundred-meter Aperture Spherical Telescope (FAST), whose performance influences the performance of the whole telescope. To avoid the information acquiring being the bottleneck of the whole process and improve the efficiency of telescope observing, 3DViewer, a program of real-time 3D visualization for Active Reflector System (ARS) of FAST based on...
This paper presents a control system for wind power generation based on LabVIEW. DSP was used in the control system. An embedded real-time operation system was transplanted into the hardware platform, which manage the control task and dispatch the multi-tasks. The control system application software in the computer was programmed with LabVIEW, which perform the measurement, control, analysis and network...
Aiming at the problem of induction motor (IM) parameters uncertainty, a novel L2 gain disturbance attenuation control algorithm based on Port-Controlled Hamiltonian (PCH) systems theory is presented for IM. Firstly, a PCH system model of IM is established. Secondly, using interconnection and damping assignment, the desired state error PCH structure is assigned to the closed-loop IM system by the energy-shaping...
Applying a novel control method of the Port-Controlled Hamiltonian (PCH) systems with dissipation, the modelling and speed tracking control of induction motor is presented when load torque is known and unknown. A PCH model of induction motor is established. The induction motor and controller are interconnected, and desired closed-loop PCH system structure is obtained by the feedback control. The desired...
A new type of oil pipe inspection robot will be presented and the structure and function movement of which will be described in this paper, what's more, the obstacle avoidance control system of the robot will be researched in the paper according to the technological problems of the inspection robot in oil pipeline. The results of the simulation experiment in VC++ environment show that the obstacle...
Power Electronic has been widely used in many fields. There are many common grounds in hardware, software and development of control system of the power electronic devices. This paper fulfilled a common digital platform for power electronic control system. DSP was used as the core of the platform, which can meet the requirement of high precision and real time. An embedded real-time operation system...
