This module introduces powerful tools for analysis and control of linear continuous-time systems. It then shows students how they can be applied to a wide range of physiological processes, providing a full understanding of the human body and the internal control systems that support life. This knowledge is then used by students to investigate and design biomedical control systems to replace or assist damaged or weak physiological processes.
The theoretical aspects covered include Laplace Transforms, Block Diagrams, Stability, Sensitivity, Root Locus Analysis, Bode Plots, Stability in the Frequency Domain, and the Nyquist Stability Criterion. The biomedical processes studied include Regulation of Blood Pressure, modelling of Lung Dynamics, modelling of Skeletal Muscle reflexes, Heart and Systemic Circulation, Regulation of Glucose and many more.
This module includes course work assignments covering both analysis and biomedical applications. It also includes labs which provide students with (1) experience of implementing a practical control system in the form of an inverted pendulum, and (2) measuring electromyographic signals from muscles, and using them to control an assistive exoskeleton device. These labs underpin the theoretical material provided during lectures and tutorials on control system design for biomedical systems.
