The rapid uptake of renewable energy sources is causing synchronous generators (SGs) to be replaced by power electronic inverters, meaning that these inverters need offer the characteristics traditionally associated with SG. As a result, it has been proposed should controlled in grid-forming mode order support voltage microgrids. Given are as source, temporary events, such short circuits or ove...

Model-based predictive control that highly depends on system parameters is widely investigated. In contrast, model-free current (MFPCC) can be performed based input or output measured data, rather than any model information, hence eliminating the influence of parameter uncertainties. such a strategy, gradients due to each possible voltage vectors are stored and used predict future currents. Cur...

Taking the feed-driven linear motor mechanism as the control object, the SIMODRIVE 611D as the control system, establish mathematical model of the servo system. The relation between feed-axis current and cutting force is presented, the current and feed-rate are separately selected as feedback and output. Around the aim of the feed-axis constant current control, choose the fuzzy control as the c...
