摘要
为了改善发电机励磁控制器的性能,应用目标全息反馈将仿射非线性系统方程中的非线性因素转换到含有控制输入的状态方程中,并得到对应的Brunovsky标准型。由于转换后的系统中非线性因素都包含在虚拟控制输入的方程中,可以通过构造二阶的ESO来观测系统中未知扰动并将其反馈线性化,进而得到线性模型。然后使用极点配置法来求得系统的线性部分的反馈增益系数。为验证文中方法的有效性,在MATLAB上进行仿真试验,仿真结果证明了该方法的可行性。
In order to obtain the corresponding Brunovsky standard type, nonlinear factors of the nonlinear af- fine system＇ equation was switched to the state equation which contains the control input factors through the targeted holographic feedback. After the switch, the nonlinear factors of system will be comprised in the sup- positional control input equation. Construct a second order ESO to observe the unknown part of system and linearize the feedback, then the linear model will be obtained. The next step is to obtain the feedback gain coef- ficient of the system＇s linear part through the method of pole assignment. Finally, MATLAB was used for sim- ulating and the result show the effectiveness of the method.
