Qualitative Concepts in Control Engineering and Process Analysis
Qualitative Concepts in Control Engineering and Process AnalysisThis will be the easiest chapter in the book. There will be no mathematics but several qualitative concepts will be introduced. First, the cornerstone of control engineering, the feedback controller is discussed. Its infrequent partner, the feedforward controller is presented. The significant but often misunderstood differences between feedback and feedforward control are examined. The disconcerting truth about the difficulty of implementing error-free feedback control is illustrated with an industrial example. Both kinds of controllers are designed to respond to disturbances, which are discussed briefly. Finally, w…
