| 摘 要： | 针对抄纸过程水分定量系统控制中的强耦合、时滞、不确定等特点,在常规PID控制的基础上提出了自抗扰控制这种新的法,方法的特点是可以动态补偿系统模型扰动和外扰,即克服了常规PID控制中存在的快速性与超调之间的矛盾.自抗扰控制器由微分一跟踪器、扩张状态观测器和非线性状态误差反馈三部分组成.最后对自抗扰控制和PID控制算法分别进行了仿真.并分析比较了这两种不同控制算法的仿真效果,结果表明自抗扰控制系统具有良好的动态性能,控制器具有很强的鲁棒性.

| Abstract: | Aiming at the features of strong-coupling,time-delay,uncertainty and others in quantification and moisture control in paper process,a new control method named Auto-disturbance-rejection controller(ADRC) has been designed based on normal PID control.The new control method can compensate system model disturbance and outside disturbance.It means that it can overcome the contradiction between fast speed and overshooting existing in normal PID very well.An ADRC is composed of three parts,which are tracking diffe... |
