Imprecise computation in real-time control systems
… of imprecise computation, caused by corrupted input and/or prematurely terminated output computation, on tracking errors for single-input-single-output and multiple-input-multiple-output time-invariant systems with deterministic errors as well as random errors. We establish the tracking error …
