Damping ratio root locus
WebRoot locus helps to determine the value of gain of the system i.e., K for any specific location on the plot, using the magnitude condition. A system can be more precisely designed if K is determined for a specific damping ratio … WebAnalyzing the accurate damping characteristic and acquiring the maximal damping ratio (MDR) curve. ... However, in order to obtain controller parameters P (i.e., proportional factor) and K pfc, different root locus diagrams are plotted. Moreover, extra current sensor is needed to realize damping ability. As a result, the system cost will be ...
