review text: As the title suggests, the book is aimed both to structures and algorithms of advanced control of industrial processes in such a manner that algorithms of advanced feedback control are mainly presented, but also on-line set-point optimization is discussed, in appropriate structures. In this respect, a starting point for the issue is a multi-layered control structure of industrial processes. This has the advantage that it allows reasonable and safe control and management through a decomposition and distribution of tasks and responsibilities into a few well-defined and simpler sub-tasks of a more homogeneous character, mutually interconnected. The basic layers of the multilayer structure are two feedback control layers (regulatory control layers) and the optimization layer. Feedback control can be carried out at two layers (especially for more complex, multivariable processes). The first and lowest one is the direct control layer (basic control layer) which has the main task to maintain the process within prescribed limits defined by the set-point values for its controllers (direct controllers). In order to avoid some emergencies, it can be equipped with certain control logic which is responsible for overriding the control designed for normal operating conditions. In certain complex processes set-points of direct controllers are under supervisory control of advanced set-point controllers. These constitute a (higher) constraint control layer, whose controllers are usually responsible for controlling certain technological constraints influencing product quality. These advanced control concepts can be materialized in real time by using Distributed Control Systems (DCS) and Supervisory Control and Data Acquisition Systems (SCADA), which enable advanced realization of feedback control tasks. Usually they are implemented by algorithms more complex than the classic PID control law. These techniques are now applied mainly at the constraint control layer, where process nonline…
