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

• The paper presents Jitterbug, a Matlab-basedtoolbox for real-time control performance analysis. The controlsystem is described using a number of connected continuous-time anddiscrete-time linear systems. The control performance is measured bya continuous-time quadratic cost function. A stochastic executionmodel is used to describe when the different discrete-time systemsare updated during the control period. Building different systemmodels, the tool makes it easy to investigate how controlperformance is affected by e.g. input-output delay, sampling jitter,output jitter, lost samples, period overruns, aborted computations,and jitter compensation.
