Control Systems with Saturating Inputs

This book presents design techniques for control system with a specific focus on robustness with respect to matched bounded disturbances, in both continuous-time and discrete-time frameworks. Includes experimental results obtained in real-world applications.

Saturation nonlinearities are ubiquitous in engineering systems: every physical actuator or sensor is subject to saturation owing to its maximum and minimum limits. Input saturation is an operating condition that is well known to the control community for its side effects, which cause conventional controllers to lose their closed-loop performance as well as control authority in stabilization. Therefore, the practical application of control theory cannot avoid taking into account saturation nonlinearities in actuators, explicitly dealing with constraints in control design.

Design techniques are presented with specific reference to robustness with respect to matched bounded disturbances, both in the continuous-time and in the discrete-time framework Some topics are rounded out with results obtained through experiments with actual plants Working examples are discussed at the end of each section with reference to the applicability of results Mathematical details which are outside the normal province of control engineers are presented in an appendix for the interested reader

Klappentext

This series aims to report new developments in the fields of control and information sciences - quickly, informally and at a high level. The type of material considered for publication includes: 1. Preliminary drafts of monographs and advanced textbooks 2. Lectures on a new field, or presenting a new angle on a classical field 3. Research reports 4. Reports of meetings, provided they are a) of exceptional interest and b) devoted to a specific topic. The timeliness of subject material is very important.
