Input shaping and VSC of container cranes
Proceedings of the 2004 IEEE International Conference on Control Applications, 2004., 2005A dual-stage control strategy for container cranes is investigated. The first stage control is a modified input shaping control to reduce residual vibrations at the target position and to limit the sway angle of the payload during the traveling. The second stage control is a nonlinear control for the quick suppression of the residual sway while ...

Equivalent circuits of MMC and VSC: Applications
IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015Equivalent circuits of Modular Multilevel Converters (MMCs) and Voltage-Source Converters (V SCs) are developed to predict that MMCs are suited for series connection for Ultra High Voltage MMC-HVDC transmission and for parallel connection as Multi-terminal MMC-HVDC. Simulations validate the predictions.

A design of chaotic servo systems by VSC
Proceedings of the 41st SICE Annual Conference. SICE 2002., 2003This paper concerns a control system design method for tracking chaotic signals. These new servo systems are designed in order to generate preferable chaos; in mechanical systems. It is shown that tracking to the chaotic signals can be achieved by LQ control and variable structure control (VSC).

A VSC algorithm based on generalized predictive control
Automatica, 1997Discrete-time variable structure control is addressed. The robustness features of sliding-mode control and the recognized benefits deriving from the anticipatory actuation associated with programmed control are combined. The transient response shaping allowed by the multistage optimization approach is enhanced by the connection of a generalized ...

New technologies of voltage source converter (VSC) for HVDC transmission system based on VSC
2008 IEEE Power and Energy Society General Meeting - Conversion and Delivery of Electrical Energy in the 21st Century, 2008This paper presents some new technologies of voltage source converter (VSC), i.e., modular multilevel VSC, for high voltage direct current transmission system based on VSC (VSC-HVDC). The origin of modular multilevel VSC and its essential working mechanism are clarified in detail.

In the case of VSC-based HVDC transmission systems, the transfer of power is controlled in the same way as in the case of a classic HVDC transmission. The inverter side controls the active power, while the rectifier side controls the DC voltage [33, 56]. With classic HVDC, the reactive power cannot be controlled independently of the active power.

The system considered in this book is given in Fig. 5.1. The HVDC system consists of two VSCs connected via a DC link. The control of converter VSC-1 is done by using DC voltage control, whereas the control of converter VSC-2 is done by active power control. In this chapter, the steady-state and transient behavior of control schemes in normal and fault

The increasing rating and improved performance of self-commutated semiconductor devices have made DC power transmission based on voltage-source power convertors (VSCs) possible. This technology is called VSC transmission. The main components in a DC scheme are depicted and their functions explained.
