Dead-Time Compensation as an Observer-Based Design
IEEE CONTROL SYSTEMS LETTERS(2022)
摘要
In this note we study discrete-time dead-time compensation from the viewpoint of the observer-based design procedure. We show that the discrete equivalent of the observer-predictor architecture can be derived ab initio via classical state-feedback and observer arguments under mild assumptions. The resulting observer is reduced order and we show that this choice is justifiable even if corresponding state measurement channels are noisy.
