Unformatted text preview: Definition of Stability Stability is an important concept in linear systems we all want to y in airplanes with stable control systems! Although many of us have an intuitive feel for the idea of stability, we need a working definition that will allow us to classify systems as either stable or unstable. Working with a partner, draft a definition of stability. The definition should be specific enough that you can test whether a system with impulse response g ( t ) (or equivalently, transfer function G ( s ) ) is stable or not. Note: There are dozens, and maybe hundreds, of definitions of stability. There is no wrong answer! When you are finished, press 1 on your PRS remote. Definition of Stability Solution G u(t) y(t) The LTI system G is Bounded Input / Bounded Output (BIBO) stable if every bounded input u ( t ) produces a bounded output y ( t ) . Basically, this definition says that every nice input produces a nice output. BIBO Stability I Consider the...
