摘要: 通过利用张动力学来处理搅拌罐的系统方程得到一组控制器,同时结合泰勒有限差分方法,对搅拌罐系统进行计算机离散控制仿真实验。此外,理论分析证明了张动力学应用到搅拌罐系统的收敛稳定性。最后,利用MATLAB仿真工具,以排空搅拌罐为例,进行了计算机离散化控制仿真实验。为了比较,基于神经网络预测控制的计算机仿真实验被给出,对比仿真实验结果证明了利用泰勒有限差分方法对搅拌罐系统进行离散化控制仿真的有效性和高精度。此外,相较于利用ode45对搅拌罐系统进行计算机控制仿真,该方法具有减少系统函数取值和易于软硬件实现的优点。

Abstract: Zhang dynamics is used to solve the system equations of the agitation tank to get controllers. At the same time, Taylor finite difference method is used in the computer discrete control simulation for the agitator tank system. In addition, the convergence stability of Zhang dynamics applied to the agitation tank is proved through theoretical analysis. In order to achieve the draining purpose for the agitation tank, the computer discrete control simulation is conducted by means of MATLAB. For comparison, the computer simulation based on the neural network predictive controller is carried out. The comparative simulation results substantiate the effectiveness and high precision of the presented method. Moreover, compared with the ode45, Taylor finite difference method can decrease system functional evaluations and has easier software and hardware implementations.

Key words: Zhang dynamics, agitation tank, Taylor finite difference, discrete control
