Process control is a statistics and engineering discipline that deals with architectures, mechanisms and algorithms for controlling the output of a specific process. This new book presents current research in the study of the problems, techniques and applications of process control. Topics discussed include the surface enhancements process of shot-peening; statistical process monitoring; data acquisition and signal processing of frequency response (FR) evaluation during plasma electrolytic surface treatments; the Markov chain approach for performance evaluation of control charts and proactive feed-forward process control.
