TL;DR: This introductory book provides an in-depth, comprehensive treatment of a collection of classical and state-space approaches to control system design and ties the methods together so that a designer is able to pick the method that best fits the problem at hand.
Abstract: From the Publisher: This introductory book provides an in-depth, comprehensive treatment of a collection of classical and state-space approaches to control system design—and ties the methods together so that a designer is able to pick the method that best fits the problem at hand. It includes case studies and comprehensive examples with close integration of MATLAB throughout the book. Chapter topics include an overview and brief history of feedback control, dynamic models, dynamic response, basic properties of feedback, the root-locus design method, the frequency-response design method, state-space design, digital control, and control-system design. A basic reference for control systems engineers.

TL;DR: The degree of success of a computer control application depends mainly on the effectiveness of the algorithm, which is generally designed from plant specifications and desired performance characteristics.
Abstract: The degree of success of a computer control application depends mainly on the effectiveness of the algorithm. Algorithms for digital computer control are generally designed from plant specifications and desired performance characteristics. If the plant is too complex for mathematical analysis, then appropriate mathematical models may be obtained using response data obtained experimentally.

TL;DR: In this article, a digital feed-forward control algorithm for tracking desired time varying signals is presented, which is particularly suited to the general motion control problems including robotic arms and positioning tables.
Abstract: A digital feedforward control algorithm for tracking desired time varying signals is presented. The feedforward controller cancels all the closed-loop poles and cancellable closed-loop zeros. For uncancellable zeros, which include zeros outside the unit circle, the feedforward controller cancels the phase shift induced by them. The phase cancellation assures that the frequency response between the desired output and actual output exhibits zero phase shift for all the frequencies. The algorithm is particularly suited to the general motion control problems including robotic arms and positioning tables. A typical motion control problem is used to show the effectiveness of the proposed feedforward controller.
