Fractional Order Motion Controls

Fractional Order Motion Controls provides a collection of practical approaches for servo control and disturbance compensation of linear and nonlinear motion systems using emerging fractional order control design methods based on fractional calculus. Covering fractional order control systems theory and its applications on motion controls by simulation and experiments, this book explains how fractional order controller design compares favourably with traditional integer order counterparts for typical motion control applications. The book also covers key topics including: stability theory in fractional order controllers design; fractional order disturbance cancellation and periodic adaptive learning control studies for periodic external disturbances; optimization and analysis approaches for nonlinear system controls and design schemes with mechanical nonlinearities such as backlash and friction. Simulation illustrations and/or experimental validations are included for each of the proposed control schemes to enable readers to develop a clear understanding of the approaches covered, and how to apply them in real-world scenarios. Key features: Proposes feasible design schemes and synthesis of fractional order controllers for motion systems with stability analysis. Includes extensive experimental results from lab bench prototype test level to industrial servo product control level . Presents material suitable for real-world applications, including hard-disk-drive track-following servo and unmanned-aerial-vehicle flight control.
