查询词典 time lag

In the control process of air conditioning systems, it is not easy to keep the objects to be desirably controlled because of their obvious features such as time lag, time-variation and nonlinearity.

This paper is mainly the dynamic input-output model that the time lag is one, which is base on the above models. After studying, we consider stochastic factor step by step in it, namely when consumption coefficient matrix is stochastic (when investment matrix is stochastic, it is almost same. So we dont research it), and they are both stochastic, then we research the stable increase solution. We utilize the means of the modern stochastic analysis and Markov process, that the stochastic dynamic input-output model don not exist the stable solution is proved. Namely, economic system must is adjusted constantly. The probability that the collapse time of the economic system is o is one.

本文对在上述基础上构造的一类时滞为1的动态投入产出模型，进行了深入研究，将随机因素逐步考虑进去，即对投入产出消耗系数矩阵为随机的情况(投资系数矩阵为随机的情况与投入产出消耗系数矩阵为随机的情况大致相同，这里就不再证明)，以及二者同时为随机矩阵时所得到的动态投入产出模型的稳定增长解问题，利用现代概率分析及马氏过程的工具，证明了不存在随机动态投入产出模型的稳定增长解；即投入产出模型反映的经济系统必须经常进行调整，其崩溃时间为无穷大的概率为零。

The simulation results demonstrate that this kind of control method is suitable for systems with time-varying parameters and time lag characteristic.

渠系运行中存在非线性、大滞后及时变性的特点。

Control algorithm as conceived by Smith with predictive functions for compensating first order delay is used to effectively overcome the large time lag and big inertia of the study object. The output of the controller is made to be attempered to the time changing property of the parameters by setting up several fixed models for the typical operating conditions and their control weightiness determined by online calculating their degree of mutual matching.

使用带有Smith预估补偿思想的一阶时滞对象预测函数控制算法，来有效克服对象的大时延、大惯性；并通过建立若干典型工况的固定模型，在线计算其模型匹配度确定控制权重，从而得到控制器的输出的方法，能适应参数的时变。
