51 PID MATLAB * 贵 州省 机 电 研 究 设 计 院( 550003) 贵州工业大学机械与自动化学院( 550008) : 模糊PID 控制仿真研究表明模糊PID 控制器具有在控制过程的前期阶段具有模糊控制器的优点, 而在控制过程的后 期阶段又具有PID 调节器的所有优势, 是一种性能优良的控制器 : PID PID Simulink :F :A 4 Study of Fuzzy PID In this paper, the fuzzy control and the PID control are combined, and the fuzzy inference method is utilized to realize the on-line auto-tuning of PID parameters. By applying the fuzzy control toolbox and the Simulink in Matlab, it takes the electric steering gear as the object to simulate. By setting the fuzzy auto-tuning controller, the paper draws a conclusion that this method surpasses Fuzzy Inference System Modeling. Build fuzzy inference systems and fuzzy trees. Fuzzy inference is the process of formulating input/output mappings using fuzzy logic. Fuzzy Logic Toolbox™ software provides tools for creating: Type-1 or interval type-2 Mamdani fuzzy inference systems. Type-1 or interval type-2 Sugeno fuzzy inference systems. The simulation model of fuzzy PID motion control was established by MATLAB software for testing to determine that the fuzzy PID position control algorithm reflects the time quickly in the motion control of palletizing robot, and the actual overshooting is small, which is more suitable for the motion control algorithm of palletizing robot. Under this condition, the modular method is adopted to Tuning-Of-Fuzzy-PID-Controllers. Fuzzy controllers are nonlinear; it is more difficult to set the controller gains compared to proportional-integral-derivative (PID) controllers. This assignment proposes a design procedure and a tuning procedure that carries tuning rules from the PID domain over to fuzzy single-loop controllers. Comparing the expressions of the traditional PID and the linear fuzzy PID, the variables are related as follows: Kp = GCU * GCE + GU * GE Ki = GCU * GE Kd = GU * GCE Assume that the maximum reference step is 1, and thus the maximum error e is 1. Since the input range of E is [-10 10], set GE to 10. You can then solve for GCE, GCU, and GU. The paper describes an effective method for determining the optimal parameters of a linear fuzzy PID controller with the use of MATLAB services, referred to as Fuzzy Logic Toolbox and Response Optimization Abstract: In this paper, the fuzzy control and the PID control are combined, and the fuzzy inference method is utilized to realize the on-line auto-tuning of PID parameters. By applying the fuzzy control toolbox and the Simulink in Matlab , it takes the electric steering gear as the object to simulate. An interval type-2 fuzzy logic-based proportional-integral-derivative controller (IT2FLPIDC) is proposed for speed control of brushless DC (BLDC) motor and performance is compared with the conventional PID and type-1 fuzzy Logic-based PID controllers in MATLAB/Simulink environment. 13 An intelligent fuzzy sliding mode controller for a BLDC motor Sensorless-BLDC-Fuzzy-PID. We investigate the control problem of BLDC motor for robot arm. The conventional controllers such as PID and Fuzzy may not be suitable for robot arm motor control because a load of motor is changed each time by various works of robot arm. To solve the problem, we propose a self-tuning PID by Fuzzy logic in this paper. In this
