For optimal model - reduction of large scale systems, up to now, the integral-square - errormethod has been developed for systems with impulse, power or sine function inputs only.
大系统的模型最优简化的积分平方误差法,至今仅仅对输入函数为脉冲、幂函数和正弦函数时有效。

Meanwhile, this paper quantitatively evaluates the design method using ISE (integral of squareerror) performance criterion.
