直流电动机的非线性控制研究

在实际应用中,直流电机本身就是一个非线性系统,它的运行状态是一个多变量、非线性、强耦合的控制对象,从电机电流和励磁的非线性变化来看,运用非线性的控制方法应该更加合理、准确。在此,以微分几何理论为基础,采用非线性控制方法,设计了一种直流电动机的输入/输出线性化控制器,并且进行了仿真,以分析其零动态特性。对被控对象精确线性化,并给出系统所需的控制规律,具有很好的调节能力和鲁棒性。

Research on Nonlinear Control of DC Motors

In practice application,the DC motor itself is a nonlinear system,whose running status is a multivariable,nonlinear and strong-coupling control object.As viewed from the nonlinear variation of the motor current and excitation,the nonlinear control methods should be more reasonable and accurate.based on the theory of different geometry,a DC motor input-output linearization controller was designed with nonlinear control method.The simulation was conducted to analyze its zero dynamic characteristics.The contro...
