| Abstract: | There is a new time delay problem between multi-processor due to asynchronous communication.System's stability is investigated by root locus.A new strategy named exponential extrapolation is proposed for the purpose of overcoming time delay of digital control system.Comparing with the conventional method,the new method reduces the impact of time delay more effectively,especially for high time delay or high fundamental supply frequency system.The research and strategy are verified by simulation and experimen... |
