This book gives a real world explanation of how to analyze the requirements for controlling a batch process, develop the control logic to meet these requirements, and troubleshoot the process controls in batch processes such as those used extensively in the pharmaceutical, biotechnology, coatings, electronic materials etc. industries.  Whereas most other books on this subject originate from the control equipment manufacturer circles, this book approaches the subject from the process perspective, with emphasis on the advantages of using structured logic in the automation of all but the simplest batch processes.
