基于不完全微分的模糊自适应PID算法速度优化控制系统设计
|
Abstract:
为提高平地机行走作业速度的控制性能，协调解决外界干扰信号对系统造成的影响以及行走作业速度精度滞后和不稳定性问题、将一阶惯性环节加入模糊自适应PID控制器的微分环节中，采用单片机作为行走作业速度的控制中心，提出了基于不完全微分的模糊自适应PID算法速度优化控制系统.最后通过Matlab的Simulink仿真软件，分别将不带PID控制、PID控制和不完全微分模糊自适应PID控制3种方式用于对人为给定速度干扰信号的控制仿真测试，验证了不完全微分模糊自适应PID算法的有效性和可靠性.
In order to improve the control performance of the walking speed of the grader, overcome the influence of external interference signals on the system, and solve the problems of precision lag and instability of the walking speed, the first-order inertial link was added, in this study, into the differential link of the fuzzy adaptive PID controller, the single chip computer was used as the control center of walking speed, and a speed optimization control system based on incomplete differentiation fuzzy adaptive PID algorithm was designed. Finally, by using Matlab's Simulink simulation software, three methods (non-PID control, PID control and incomplete differential fuzzy adaptive PID control) were respectively applied to the control simulation test of the artificial speed disturbance signal, which verified the effectiveness and reliability of the incomplete differential fuzzy adaptive PID algorithm
