| Abstract |
A parallel-working multi-transputer network and a parallel-processing software algorithm for a complete digital control of a squirrel cage induction motor will be presented. Practical results for a position controller achieved with a transputer network consisting of three transputers are given. Based on this system different sample ratios for a position cascade controller are compared. Furthermore the dynamic behaviour of position step responses as a function of the complete control cycle time is researched. The control cycle time of the multiple value controller is minimized down to 192 μs. Therefore a new parallel processing field orientated control method using the "prefetch-technique" will be introduced. The real time controller uses the IEEE single floating point format (REAL32). |
