The aims of this module are to introduce the students to the design and analysis of computer feedback control systems with an emphasis on the design of digital compensators and implementation issues.
Syllabus: Discrete-Data Theory: *Introduction to the key features of digital control and some of the problems to be addressed. *The theory of sampling, non-ideal and ideal sampling. *Frequency spectrum of a sampled signal, Nyquist sampling rate, aliasing. *Data reconstruction - from sampled signal to continuous-time signal, Zero-order hold. *The Z-transform, relationship between the s-plane and z-plane. *Properties of the z-transform. The pulse transfer function. *The inverse z-transform - 4 methods - (i) power series (ii) partial fractions (iii) residues or inversion integral (iv) difference equations *Stability considerations. W-plane, Hurwitz-Routh.
Design of Control Algorithms: *Overview of Design Techniques *Direct Design in the Z-domain *Discrete PID
Implementation Considerations: *Realisation of algorithms using direct, cascade and parallel forms. *Quantization Effects *Selection of the sampling time, T. *Hardware and software considerations, interfacing, hardware options.
