摘要
针对风力摆装置存在的不确定性和非线性因素,考虑到传统PID控制方法很难对其进行精准有效的控制,为此将传统的PID控制和模糊控制思想相结合,提出了基于模糊切换的多模控制器设计方法来解决其稳定性问题。多模控制器是对风力摆装置反馈输入的角度误差和误差变化率进行处理,并采用模糊切换开关自动调整各控制器的控制强度,由此提高风力摆装置的自适应能力。最后,通过MATLAB仿真工具,将所提出的多模控制器分别与常规PID控制器和模糊控制器进行对比,验证了所提出方法的有效性和优越性,进一步证明了多模控制器具有较高的抗干扰性和精准性等优点。
In view of the uncertainty and nonlinearity existing in the wind pendulum device, combining the traditional PID control theory with fuzzy control thought, a multi-mode controller based on fuzzy switching to solve the stability problem is proposed, since the traditional PID method is difficult to control pendulum device accurately and effectively. The multi-mode controller is obtained to deal with the angle error and the error change rate of the feedback input of the wind pendulum device.The control intensity of each controller is adjusted automatically by using the fuzzy switch so as to improve the adaptive ability of the wind pendulum device. Finally, by using the MATLAB simulation tool, the multi-mode controller with the conventional PID controller and the fuzzy controller are simulated and compared respectively. The effectiveness and superiority of the proposed method are illustrated which further proves that the multi-mode controller has the advantages of high anti-interference and high precision.
