According to the control mode of flexible structure, it can be divided into active and passive flexible vibration control. These technologies do not rely on the supply of external energy to absorb heat to achieve vibration damping. Traditional PID controllers have the advantages of simple structure, stable work and good reliability, and have been widely used in accurate mathematical control systems. When there is multivariation, nonlinearity, and hysteresis, it is difficult for traditional PID controllers to achieve the desired results. Due to the improvement of technical level, control technology has received more and more attention, and various new types of fuzzy controllers have emerged. However, a single fuzzy control method has the disadvantages of weak control effect and control accuracy that cannot meet the design needs. Traditional PID control combined with adaptive fuzzy control can solve these problems well, by feeding back the error and error correction rate of the operating system to the fuzzy controller, and dynamically adjusting the proportion, integration and differential parameters of the PID controller, so that the whole system is in the optimal working environment. Finally, a fuzzy controller is built in Simulink to achieve a better control effect.
