To understand a number of power system phenomena and to predict critical conditions in system operation, such as voltage collapse, a real-time simulator able to model the dynamic behavior of large power systems has been needed for a long time. The need for real-time simulations stems from the fact that in many practical situations it is desirable to test new equipment and analyze the dynamic behavior of a large power system using the actual pieces of equipment. A new digital simulator was developed based on a hypercube-type massively parallel computer to achieve this objective. The new simulator features: (1) real-time simulation of a large power system which covers transient stability through long-term behavior with constant accuracy level; (2) user-friendly man-machine interfaces which mimics an actual operating environment and realtime data presentation on a CRT; and (3) high-speed digital/analog conversion interfaces which connect the digital simulator to actual equipment. 相似文献

The goal of this contribution is to use a three dimensional (3D) full-band particle-based simulator to investigate 3D scaling effects of static and dynamic current-voltage characteristics of GaAs MESFET structures. The full-band particle-based simulator is also applied to a novel dual-gate GaAs MESFET structure. 相似文献

A digital simulator based on a hypercube-type massively parallel computer, the NCube2, has been developed. The simulator features: real-time simulation of a large power system which covers transient stability through long-term behavior with constant accuracy level in root mean square values; user-friendly man-machine interfaces which mimic the actual operating environment including interactive setting of several system parameters and real-time data presentation on a CRT; and high-speed A/D (analog to digital) converters, D/A (digital to analog) converters, and D/IO (digital input and digital output) interfaces are used to connect the digital simulator (power system dynamic model) to actual equipment. The authors describe the basic characteristics of the digital simulator and present results obtained in real-time simulations 相似文献

Double closed‐loop control with adaptive strategy for automotive engine speed tracking system 下载免费PDF全文
Meiyu Feng Xiaohong Jiao 《International Journal of Adaptive Control and Signal Processing》2017,31(11):1623-1635
In order to improve the transient and static performances of an engine speed control system in a wide speed range, this paper presents an adaptive double closed‐loop control strategy. The control scheme possesses intake manifold pressure inner closed‐loop adaptive proportional‐integral control and engine speed outer closed‐loop adaptive proportional‐integral control for achieving the tracking precision in a wide range of speed, as well as adaptive nonlinearity and feedforward compensators for overcoming parameter uncertainty and nonlinearity. The whole closed‐loop system's stability and the speed tracking convergence are ensured theoretically by the Lyapunov stability theory and the LaSalle invariant principle. The effectiveness of the proposed control strategy is validated through the operation results on the simulator of a V6 engine exploited by the Research Committee of the Society of Instrument and Control Engineers of Japan. 相似文献
