Control systems with saturating inputs: analysis tools and advanced design

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 thecontrol 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 withrespect 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. INDICE: Introduction. Estimation of the null controllable region: Continuous-time plants. Estimation of the null controllable region: Discrete-time plants. Control Design Issues: Continuous-time plants.
