Abstract:
The paper deals with the best choice for the control sampling period in term of a multicriterial conditioning, with the on-line timing and with a comparison between the conventional (like PI) control algorithms and the fuzzy control. Several useful relations are followed by diagrams obtained in simulation and by different real-time recordings both for the timing and for characteristic variables of the system. Implementations with microcontroller and DSP are used for analyzing the design criterion and the timing strategy. The application field concerns a servodrive, so the real-time constraints are quite strong. The author conceived a general control strategy for the on-line timing based on imbricate interrupts, each pulse encoder acting on the hardware input interrupt of the control processor.
