Jitterbug: A Tool for Analysis of Real-Time Control Performance

Bo Lincoln, Anton Cervin


The paper presents Jitterbug, a Matlab-based toolbox for real-time control performance analysis. The control system is described using a number of connected continuous-time and discrete-time linear systems. The control performance is measured by a continuous-time quadratic cost function. A stochastic execution model is used to describe when the different discrete-time systems are updated during the control period. Building different system models, the tool makes it easy to investigate how control performance is affected by e.g. input-output delay, sampling jitter, output jitter, lost samples, period overruns, aborted computations, and jitter compensation.
