The main drawback of traditional application is that a brake system built in an AC servo driver is triggered under a fixed detection level of PN-BUS voltage, which causes malfunction occasionally, and therefore burns out the internal brake resistor. In order to reduce the probability of malfunction of braking controller and improve the accuracy of the regenerative braking system, the fuzzy algorithm is considered a solution in this paper. The experimental results show that fuzzy algorithm-based application proposed in this paper not only can achieve a significant variable duty detection level on PN-BUS voltage, but also works in a firmware-based operation to avoid from resistors burnout.
