The Motor Control industry is a strong aggressive sector. Each industry to remain competitive, must reduce costs but also has to answer to power consumption reduction and EMI radiation reduction issues imposed by governments and power plant lobbies. The results of these constraining factors are the need of enhanced algorithms. DSP technology allows to achieve both, a high level of performance as
