Robustness<br />
A closed-loop system exhibits robustness if its response characteristics are<br />
insensitive to parameter variations and noise.<br />
Parameter variations are likely to occur through normal wear<br />
Expected wear should be considered as part of the overall life cycle design<br />
Noise may depend on environment and operating conditions<br />
Gain and phase margins are traditional measures of robustness<br />
Gain margin measures tolerance to loop gain variations<br />
Phase margin indicates tolerance to loop phase variations<br />
Phase margin also measures tolerance to loop time delay<br />
Other robustness tests are possible using a model simulation<br />
Consider random variations in each model parameter<br />
Robustness results become part of your system's performance specification<br />
