Talk:Control Systems/System Specifications

==System Specs

Classical specs include quarter-decay, overshoot and rise time. Modern ones include the ISA IAE (integrated absolute error) and ISE (integrated squared error). Sometimes there are tight constraints on the output range of the control. A variant of IAE is the CQI (control quality index) which normalizes the IAE to the maximum error possible within output clamps, and is ranged 0-1, with 1 being perfect tracking to setpoint.--Billymac00 18:12, 30 November 2006 (UTC)
