摘要
通过实验手段及机理建模法获得多容水箱液位控制的分段线性化数学模型,从而采用T-S型模糊算法构成控制器,不仅能在每个模糊子区间中建立分段线性模型,还能借助隶属度函数将各分段线性模型平稳地连接成一个整体非线性系统模型,有效克服参数突变而引起的扰动,进一步提高控制系统动态响应性能。
To obtain a plurality of accommodating piecewise linear mathematical model of water tank liquid level control by means of experiment and mechanism modeling method, and T-S type fuzzy algorithm using fuzzy controller is composed of, can not only establish a piecewise linear model in each sub interval, but from the membership function of each segment linear model smoothly connected into a whole nonlinear system model parameters, effectively overcome the mutation induced perturbation,further improve the performance of control system dynamic response.
