A 16/24-bit DSP-ASIC coprocessor for AC motor modelling
A discrete-time computational AC motor model is derived and analyzed for the purpose of advanced motor control. The starting point is a continuous-time model defined by a pair of simultaneous complex-coefficient differential equations. The discrete-time model is derived using the forward-difference (FD) approximation. The exact dependence between stability and the minimum sampling rate in the FD approach is shown. An efficient implementation architecture is given, based on DSP techniques. A 16/24-bit DSP-ASIC coprocessor prototype implementing the AC motor model is introduced.<>
