Output feedback controllers of suboptimality degree beta Academic Article uri icon


  • This technical note points out a misconception in the recent paper by Zheng (1] about suboptimal output feedback control. We develop a new synthesis method for designing output feedback controllers of suboptimality degree. These controllers yield a cost value equal to or less than a scalar multiple () times the cost value obtained by optimal LQ state feedback control. 1990 IEEE
