The control system in human brain generally exerts the goal‐directed regulation on a variety of mental processes. To deal with different control demands, these brain areas of the control system, especially the dorsolateral prefrontal cortex (DLPFC), may be flexibly recruited across different tasks. However, few studies have investigated how the flexibility of the control system is realized during...
In order to solve the imbalance and overload of electricity grid caused by starting multiple Resistance Welder Machines, the text puts forward a solution of having batch and time-sharing control over Resistance Welder Machines by means of Programmable Controller (PLC). This solution increases the stability and flexibility of control. In addition, the system hardware design and software process are...
This paper presents a detailed comparison between two voltage source converter high-voltage dc transmission systems. The first is based on the neutral point-clamped converter (also known as HVDC-Light) and the second is based on a modular multilevel converter (known as HVDC-Plus). The comparison focuses on reliability issues of both technologies, such as, fault ride-through capability and control...
To improve the control system performance of wheeled autonomous mobile robots, an embedded control system was designed and implemented with advanced microprocessor. Based on the hierarchical control method, two processors were applied to different control levels so as to attain complicated high-speed algorithm and real-time control. Multiple sensors were introduced to sense the environmental conditions...
