| 摘 要： | 气动加载系统是复杂的非线性时变系统,可变参数和不确定性比较多,本文采用积分型线性自抗扰控制器(I--LADRC)对气动加载系统进行控制.自抗扰控制器(active disturbance rejection controller,ADRC)结构简单,不依赖于被控对象精确的数学模型,可以很好补偿被控系统内外各种不确定性.加入积分环节用来弥补ADRC在时变系统控制中存在的不足.在采用VC++6.0的工控试验平台上,将I--LADRC应用于气动加载系统中,分别在加载压力为恒值、方波和正弦波时进行空载和加载实验,并将得到的实验结果与PID控制算法进行比较,实验结果表明该控制算法不仅响应速度快,精度高,并且还具有较强的鲁棒性,具有良好的工程应用前景.

| Abstract: | The pneumatic force control system is highly nonlinear system with variable parameters and uncertainty. In this paper, an Integral-Linear Active Disturbance Rejection Controller (I-LADRC) is proposed for a pneumatic force control system. The ADRC with simple structure less depends on the mathematic model of the system and can be well compensated internal and external uncertainties. An integral part is added to compensate for the lack of ADRC when it is used to control time-varying systems. The I-LADRC was used to control the pneumatic force control system without load and with load. The experiment results compared with that of PID denominate that the controller not only has fast response, high precision, but also has strong robustness. |
