methodology. We then provide a systems perspective of the rendering process
and explain the impacts of variables surrounding the system inputs and outputs.
After that, a survey of previous research in the areas of rendering load control and
characterisation is discussed.
Chapter 3 delves into the details of our data-driven modelling approach to
real-time rendering with a focus on linear system structures and their derivation.
Through experiments, we provide rendering models for single-input-single-output
(SISO) systems and show how they may be extended to more complex and practical
systems involving multiple inputs.
In Chapter 4, we explore the use of soft computing techniques for modelling
the real-time rendering process. The application of such techniques is performed
at the operating range of the rendering system where non-linear characteristics are
exhibited. Following that, we provide the basis for linearisation from the derived
non-linear rendering system model.
Chapter 5 begins with the introduction of model-based control and deals with
the control system framework for the linear rendering system model obtained in
ChapterĀ 3. The key control mechanism discussed in this chapter is the closed-loop
feedback design with PID controller. We demonstrate how systems with single and
multiple inputs may be controlled as well.
The focus of Chapter 6 is on advanced control techniques and considers our pro-
posed framework from a model-less perspective. This chapter illustrates the estab-
lishment of a control system framework without the need for an explicit system
model as described in Chapters 3 and 4. By using a variety of fuzzy control tech-
niques, we demonstrate that a control system can perform very well when tracking
the performance of a real-time rendering process.
Chapter 7 discusses applications, challenges, and possibilities, including system
architectures, software and hardware performance and future technology.
The conclusions of our research and suggestions for future work are discussed in
Chapter 8.
