52667 与规范的实现矩阵求解方法相比,新方法通过在传递函数特征多项式的图结构中添加两种类型的顶点,能够得到F-M II状态空间模型的一组完整的实现矩阵,而不是只有一个实现, Compared with the canonical form method, the proposed algorithm adds two types of vertices to the digraph of characteristic polynomials, a group of realization matrices of the F-M II state space model can be obtained instead of only one realization.
52668 且获得实现矩阵的阶次更低,避免了复杂的矩阵计算过程, And the order of the realization matrix is relatively low, avoiding the complicated matrix calculation process.
52669 使得系统表现形式更加清晰直观,有利于多维系统的设计和分析。 The new method makes the system expression more clear and intuitive, and facilitates the design and analysis of multi-dimensional systems.
52670 对所提出的方法,本文给出了具体的数例说明其可行性。 For the proposed method, specific examples are given to illustrate its feasibility.
52671 当液位控制系统中加入流量扰动后,经典控制理论中的前馈控制是使前馈环节与闭环系统的传递函数之积为1、使输出完全复现输入。 When the flow disturbance is added to the liquid level control system, the feedforward control in the classical control theory is to make the product of the feedforward link and the transfer function of the closed-loop system be1, so that the output can fully reproduce the input.
52672 由于控制系统内部各环节间存在非线性,以及对建模精度要求较高,在工程上难以实现。 Because of the nonlinearity in the control system and the high requirement of modeling accuracy, it is difficult to realize the feedforward control in engineering.
52673 本文基于液位控制系统,提出利用实际工况参数,调节阀阀位、管路中流量与水箱液位来确定前馈补偿系数。 Based on the liquid level control system, this paper proposes to determine the feed-forward compensation coefficient by using actual working condition parameters, regulating valve position, flow rate in pipeline and liquid level of water tank.
52674 其中调节阀阀位与管路中流量大小由调节阀的流量特性曲线所决定。 The control valve position and the flow in the pipeline are determined by the flow characteristic curve of the control valve.
52675 在实际生产中,阀位与流量之间存在非线性关系,从而导致不同液位、不同干扰大小下的前馈补偿系数不一致, In actual production, there is a non-linear relationship between valve position and flow rate, which leads to the inconsistency of feed-forward compensation coefficient under different liquid level and different interference.
52676 即在某工况下计算的前馈补偿系数并不能适用于其他工况。 That is, the feedforward compensation coefficient calculated under certain working conditions cannot be applied to other working conditions.
