This study explains and demonstrates the design method for a control system with a load disturbance observer. Observer gains are determined by linear programming (LP) in terms of the Routh-Hurwitz stability criterion and the final-value theorem. In addition, the control model has a feedback structure, and feedback gains are determined to be the linear quadratic regulator. The simulation results confirmed that compared with the conventional method, the output estimated by our proposed method converges to a reference input faster when a load disturbance is added to a control system. In addition, we also confirmed the effectiveness of the proposed method by performing an experiment with a DC motor.
本研究解释并展示了一种具有负载干扰观测器的控制系统的设计方法。观测器增益通过线性规划(LP)根据劳斯-胡尔维茨稳定性判据和终值定理来确定。此外,控制模型具有反馈结构,反馈增益被确定为线性二次调节器。仿真结果证实,与传统方法相比,当控制系统中添加负载干扰时,我们提出的方法估计的输出更快地收敛到参考输入。此外,我们还通过使用直流电机进行实验来验证了所提出方法的有效性。
