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

同时本文采用ISE(误差平方积分)性能指标量化地评价了这种设计方法。

For optimal model - reduction of large scale systems, up to now, the integral-square - error method 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。
