Flexible manipulators are widely used in overhead cranes for industrial purposes and accurate control of the tip point of such a system is very difficult.
本文利用MATLAB的模糊逻辑工具箱(Fuzzy Logic)设计模糊控制器,并用MATLAB提供的simulink进行仿真。 隶属度函数的建立:设控制系统的输入为单位阶跃信号r,输出为y,误差为E,误差变化为EC ;PID控制器的输入为Kp、Ki、Kd。 设置E,EC所取的论域分别为{0,3,6,10}和{0,2,4,6},其模糊子集为{B,M,S,Z},分别表...
This example compares a type-2 fuzzy PID controller with both a type-1 fuzzy PID controller and conventional PID controller. This example is adapted from [1]. Fuzzy PID Control This example uses the following fuzzy logic controller (FLC) structure as described in [1]. The controller is ...
Create a type-2 fuzzy logic PID controller and compare its performance with a type-1 fuzzy PID controller and a conventional PID controller. Ports Input expand all in—Input signal scalar | vector Output expand all out—Defuzzified output signal ...
The application of a simple microcontroller to deal with a three variable input and a single output fuzzy logic controller, with Proportional - Integral - Derivative (PID) response control built-in has been tested for an automatic voltage regulator. The fuzzifiers are based on fixed range of the...
[13]. To overcome this weakness, the application of a fuzzy logic design is recognized as one of the most effective PI/PID controller design methods in the presence of nonlinearity [14,15,16] and including PV and wind turbine plants [17], making the FPID an expandable controller. The ...
