| 中文摘要 |
| 鉴于热连轧活套系统的典型特性: 多变量、非线性和强耦合, 使其控制相对复杂. 采用角变化法得出张力
力矩表达式, 并通过对活套套量和张力力矩关系式进行增量化, 得出活套系统数学模型. 采用自抗扰控制技术, 应
用扩张状态观测器实时估计扰动, 将活套套量和张力的耦合归结于对系统的“总扰动”的一部分进行估计并给予
补偿. 仿真表明, 相比于PID 控制算法, 此算法具有可行性和有效性. |
| 英文摘要 |
| From the control point of view, the hot strip rolling looper system has the characteristics of multivariable,
nonlinear and strong coupling, which make the looper control complex. The expression of tension moment is obtained
by the angle variation method, and the looper system mathematical model is obtained with the incremental of loop and
tension torque relationship. In order to estimate the disturbance in real time, the extended state observer (ESO) of the active
disturbances rejection controller (ADRC) is used. In addition, the coupling of the looper height and tension dues to a part
of the ”disturbance” which is estimated and compensated in the system. Compared with PID control algorithm, simulations
show that the ADRC is more feasible and effective. |
