The transfer function approach is widely used in classical control theory for its easy handling and physical meaning. Although the use of transfer functions is well-established for linear time-invariant systems, it is not suitable for non-stationary systems among which are sampled-data systems and processes with periodically varying coefficients. Computer-controlled continuous-time processes are a very important subset of periodic sampled-data systems which are not treatable using ordinary transfer functions.
Having established the ability of the parametric transfer function to solve this problem for single-input, single-output systems in previous work, the authors extend these methods, which incorporate time-dependence, to the idea of the parametric transfer matrix in a complete exposition of analysis and design methods for multiple-input, multiple-output (MIMO) sampled-data systems.
Multivariable Computer-controlled Systems is divided into three parts:
Appendices covering basic mathematical formulae and the description of two MATLAB(r) toolboxes round out this self-contained guide to multivariable control systems.
Of special interest to researchers in automatic control and to development engineers working with advanced control technology, Multivariable Computer-controlled Systems will also interest mathematical control theorists and graduate students studying advanced methods of computer-based control.
Why Bishops? What's so special about Bishops? What are Bishops called to and how best can they do it? This book is the single resource of answers to all the questions one could conceivably have about what a Bishop is and their function and purpose in the Church.
Paul Avis offers a fascinating account of the ministerial identity of the bishop, and in particular the tasks and roles of episcopal ministry. Placing the Bishop within his wider ecclesiological framework, Avis illuminates the role of the individual in episcopal ministry. The book sets the vital work of a Bishop within an ecclesiological framework: the Bishop in the Anglican Communion, within the Church of Christ, within the purposes of God.
