A Note on Control Area

摘要

Control area, or the integrated error for a step function input, has been used as a measure of control system performance. For systems described by θ0(s) θi(s) =e-sTd (τ1s+1)(τ2s+1)…(τms+1) (T1s+1)(T2s+1)…(Tns+1) , it is proved that the control area is A=Td+n∑i=1 Ti-m∑i=1τi. A simple method of evaluation is presented and some limitations of the control area criterion are mentioned.
