This paper focuses on the systematic design and development of an optimized embedded system platform from ground up to handle special real-time requirements of control applications. An embedded system is usually embedded as a part of a complete device including hardware and mechanical parts, and both the hardware system and the software system are tailored and optimized to realize specific functions...
Air canard was controlled by servo mechanism when traditional tactical missile was flying in atmosphere. However, it cannot meet the requirement of the low cost and small missile body applications. This paper proposed a new method of guided mortar control, which makes use of the aerodynamic force as the power resource of the power mechanism. Control force was generated by controlling differential...
The paper firstly establishes a port-controlled Hamiltonian dissipation (PCHD) based model of a direct-drive permanent magnet synchronous generator (D-PMSG). A new double loop control of the D-PMSG is proposed with the outer speed loop controlled by a non-singular higher-order terminal sliding mode (NHTSM) controller to undertake maximum wind power point tracking (MPPT). In the inner current control...
Software-defined network (SDN) is the next generation of networking architecture that is dynamic, manageable, cost-effective, and adaptable, making it ideal for the high-bandwidth, dynamic nature of today's applications. In SDN, network management is facilitated through software rather than low-level device configurations. However, the centralized control plane introduced by SDN imposes a great challenge...
The control method of microgrid should be flexible due to its special operation modes and the differences of micro sources. Considering the coordinated control of micro sources in different operating modes and the smooth transition between the operating modes, an improved P-f and Q-V droop control method and the design method of controller are proposed in this paper. This method can realize the synchronous...
For the defect of traditional voltage and reactive power control of substation based on “Nine-Area Diagram” control strategy, presence of transformer fitted with OLTC and capacitor banks switching frequently have certain impact on the voltage of distribution system. In addition, its range of adjustment is major and it can't realize surpassingly accurate adjustment for voltage and reactive power. Based...
Abstract-With the development of new energy, solar photovoltaic power plants have been widely established across countries, and more rigorous demands have been required on its management technology. This paper aims to introduce the design of measurement and control system of solar photovoltaic power plant, expound its operating principle and structure, focus on the design of each component in this...
Combustion system of CFB is a large time delay, strong coupling, multiple input and multiple output, nonlinear time-varying system. Its dynamic characteristic is very complex. Good control effect cannot be achieved using traditional control method. Many studies have shown that using intelligent control method in CFB can lead to better outcome. But intelligent control method cannot be achieved in DCS...
This article describes the control system of time-sharing for Heavy Ion Research Facility of Lanzhou (HIRFL). It describes in detail mainly of the overall system architecture, hardware and software. The control system provides a guarantee for multiple terminals operation and improves the beam availability and efficiency.
A classical wind energy conversion system is usually a passive generator. Its power does not depend on the grid requirement, but entirely on the fluctuant wind condition. In this paper a DC-coupled wind/hydrogen/super-capacitor hybrid power system is studied. The purpose of the control system is to coordinate these different sources, especially their power exchange, in order to make the generated...
With the network technology development, remote technology is gradually occupying the technology mainstream. It has become more and more popular in the home office and distance education. The rapid development provides a broad world to the remote control software. Pcanywhere, damewhere, QQ remote assistance, and other remote-control software have emerged. In remote control, improving efficiency and...
Wide-area measurement system (WAMS) provides a platform for more efficient control, and some discontinuous types of wide-area control projects have been reported in commission in the recent years. In this paper, a continuous type of wide-area damping control system (WADCS) is introduced, which is used to suppress the inter-area oscillations in a complicated real power grid by modulating multiple HVDC...
