Aiming at the Z-source inverter used in the micro-grid and its grid-connected control research, the photovoltaic system was taken as the example. The inverter integrated three functions including MPPT (Maximum Power Point Tracking), step-up/down DC-side voltage and output grid-connected. In order to overcome the system instability caused by zero point of Z-source net in the right half-plane, the paper...
A highly-efficient, low budget and lower power coal mine security control system based on wireless sensor networks was put forward in the paper. The overall structure of the monitoring system, hardware design of the notes, topology structure of the wireless sensor networks and the workflow of the system was stated. This system is not only monitoring various kinds of situations under the coal mine,...
Usually on-off magnetism team motor speed-adjusting adopts traditional linear control algorithm (such as PID). In modern control system, it is nonlinear, multivariable, multi-coupling, high-dimension and the object is time-varying, uncertain and difficult to describe by math model because of the complex control object. The traditional algorithm is difficult to meet the need of on-off magnetism team...
