Offering a professional and modern view on process modelling, system identification and automatic control of physical and industrial processes, this is the first comprehensive text augmented with practical examples and their solution with MATLAB code to cater to the needs of engineering students of all levels. The book presents the topics of modelling of physical systems based on first principle with material and energy balances, Formulation of transfer functions and model structure with parametric identification supplemented by software, question and answers along with exercise problems. In order to address modern process control issues in process industries various topics are covered along with the associated mathematical tools to solve models involving ODE/PDE, optimization tools, transient behaviour of processes and transfer functions. This text explains auto tuning of PID controllers and related analysis for process identification for the first time using relay feedback by experts.
