那就是你的均方根。
The paper proves that optimal controllers can stabilize the exponentially mean square of networked control systems.并证明了该最优输出反馈控制律可使网络控制系统均方指数稳定。
The results of the test data indicate that the prediction system is reliable and the root of mean square error is about 15%.对测试数据的预测结果表明,该预测系统能够可靠工作,预测结果的均方根误差在15%左右。
