Additionally, the new products offer automatic power standby for greater energy efficiency, passive cooling to provide increased reliability, high frequency compensation to offset interference from metal in the building's infrastructure, intelligent input offering dynamic control, as well as self testing for early fault identification.
Divided into five main parts: introductory material on control systems, including frequency domain analysis and examples from the fields of unmanned aircraft vehicle and wind energy control systems; an extensive and in-depth study of analog control systems, with many example algorithms and rigorous mathematical foundations; a part on analog systems compensation, including root-locus and frequency compensation design; several chapters that do not easily fit under other headings, gathered here as "Advanced topics", including control-ratio modeling, closed loops and state-variable feedback design and parameter sensitivity problems; and an overview of digital control systems.
