摘要：Current measurement is one of the most important work in online monitoring of the electric system. Self-powered and intelligence are key areas of the current measuring sensor. In this paper, a self-powered current measuring sensor realizing measurement and power supply synchronously was designed. The different functions of current transformer were integrated and the mathematical relationship between the line current and the CT secondary side output was deduced. The model for current measurement based on different signals before or after the rectifier bridge was constructed. The overall design of the current measuring equipment was given. Finally, the accuracy of different measuring models was verified by experiments and test results under load changes were analysed.
其他摘要：The article analyses possible ways of using predictive controllers to perform control tasks and dynamic decoupling for dynamic systems with Multiple Inputs and Multiple Outputs (MIMO). The results of experiments on the selected reference plant are presented, showing the effectiveness of individual decoupling methods. These are also compared to those obtained in typical control systems with Proportional-Integral-Derivative (PID) controllers. Recommendations are made on how to tune model predictive controllers (MPC) for their effective use for MIMO plants. DOI: 10.5755/j01.eie.25.2.23195
