This book featuring, new approaches for controller tuning, control structures and configurations for more efficient control, practical issues in PID implementation, and non-standard approaches to PID including fractional-order, event-based, nonlinear, data-driven and predictive control, the nearly twenty chapters provide a state-of-the-art resumé of PID controller theory, design and realization. Each chapter has specialist authorship and ideas clearly characterized from both academic and industrial viewpoints.
