THE INTER-RELATION OF SAMPLING AND TRANSPORT LAG IN DETERMINING CONTROL SYSTEM STABILITY

THE EFFECTS ON THE STABILITY OF CONTINUOUS FIRST AND SECOND-ORDER SYSTEMS DUE TO PURE TIME DELAYS IN THE CONTROL LOOP ARE EXAMINED AND STABILITY BOUNDARIES ARE PRESENTED. SIMILAR STABILITY BOUNDARIES FOR SAMPLED FIRST AND SECOND- ORDER SYSTEMS ARE PRESENTED AND COMPARED AGAINST THE BOUNDARIES FOR THE CONTINUOUS CASE. THE EFFECTS OF THE TIME DELAY IN A SAMPLING SYSTEM ARE FURTHER INVESTIGATED IN THE Z PLANE BY MEANS OF ROOT LOCI WITH TIME DELAY AS PARAMETER. DERIVATION OF THE ROOT LOCI PRODUCE FORMULAE WHICH COULD BE USEFUL FOR SYNTHESIS ON THE Z PLANE. COMPUTATIONAL VERIFICATION IS PRESENTED THROUGHOUT AND FROM THE ANALYSIS THE ADVANTAGES AND DISADVANTAGES OF HAVING A SAMPLER IN A SECOND-ORDER SYSTEM ARE CONSIDERED. /AUTHOR/
