| 中文摘要 |
| 主要研究新颖实用非线性自抗扰控制算法, 在结晶器多变量耦合系统中的应用. 自抗扰控制主要特性是实时估计对象模型摄动和外扰的总和作用量, 并在控制信号中补偿掉, 实现不确定性强非线性对象的实时动态反馈线性化. 结合控制对象, 建立了结晶器多变量耦合自抗扰控制系统. 数值仿真试验表明自抗扰耦合控制的协调性、自适应跟随性和抗干扰性优于传统的PID解耦控制. |
| 英文摘要 |
| A new nonlinear control algorithm-active disturbance rejection control (ADRC) is introduced, and a new ADRC control scheme for mould multivariable coupled system is proposed in this paper. The key element of ADRC is extended state observer (ESO). The real-time dynamic linearization is then implemented by disturbance estimation via ESO and disturbance compensation with control law. The mould multivariable coupled system based on ADRC is also established in combination with control objects. Finally, the principal analysis and simulation results show that the ADRC coupled control scheme not only has good coordination, but also provides satisfactory performance outperforming the traditional PID decoupling control. |
