external controller meaning in English
外舵
Examples
- Both the inner controller and external controller are used to satisfy the required tracking performance . the proposed control scheme has a rigorous theoretic base . the controllers designed not only guarantee the stability robustness and performance robustness of the system but also the tracking performance of the system
所提出的控制方案有严格的理论基础，既保证了闭环系统的稳定性和快速的跟随性能，又抑制了模型摄动及外部干扰对系统的影响，保证了系统的鲁棒性能。 - The innovative ideas in this paper are that robust h control theory based on conventional ip controller is applied to the high - precision feed of a single axis , and the controlled plant is composed of ip velocity loop and two - order model of linear motor . a constraint condition on y in the problem of h2 / h is deduced from the frequency criterion of riccati equation , which makes the repeated computation on r simple . considering the two - loops control problem , the h state feedback controller based on ip controller as the inner controller is applied to satisfy the velocity performance of the system , and a pi controller , the external controller , is used to satisfy the position performance
本文的创新之处在于将传统的ip速度控制器和直线电动机的二阶模型作为一个广义的被控对象，利用鲁棒h _控制理论设计了一个h _状态反馈控制器，以此解决高精度进给的控制问题，并在此基础上研究了h _ 2 h _混合控制问题，结合h _代数riccati方程正定镇定解存在的频率判据，推出了一个控制器存在的约束条件，使以往须反复试探的，有了更进一步的约束范围，简化了计算。
