Research On Control Method Of Tuned Mass Damping System

The most ideal components that constitute a traditional mechanical system are three parts: mass,damper and spring.The damping system composed of these three parts is the most classic and common mechanical system in the algorithm,and the system can be applied to various fields in life.For example,during the docking process in space,the stability of the equipment and the impact resistance capacity will have a direct impact on the result of the docking.In summary,it is necessary to study the spring damping system.This subject will use active disturbance rejection control and PID control algorithms to achieve stable control of the secondary mass-spring-damping system,and apply the experimental platform to the automatic control teaching,so that the equipment is no longer single in the teaching process and the experiment is more intuitive.Focusing on this task,this topic will be studied from the following aspects.Firstly,we extensively consult the relevant materials of the mass-spring-damping system,understand its structural characteristics,design the hardware structure of the secondary mass spring damping system,and use Lagrangian modeling method and mechanism modeling method to realize its mathematics.The establishment of the model and the performance analysis of the established model prove that the model has controllable and observable characteristics.Secondly,the adaptive disturbance rejection controller is constructed to realize the design of differentiator,state observer and nonlinear error feedback controller for tracking trajectory signal.The PID controller is built to realize parameter tuning and the simulation experiment is completed in Simulink environment.Experimental results show that both schemes can achieve stable control of the system,but compared with the PID controller,the ADRC has obvious control advantages.Collect input and output data to provide data basis for identification.Because the v-gap recognition method uses the frequency domain signal,but the spherical plate system directly collects the time domain signal.Therefore,Fourier transform is needed to convert the time domain signal to the frequency domain signal.Thirdly,built the software platform and hardware platform of the system,realize the operation of the host computer program through LABVIEW,use the experimental platform to analyze the system in the frequency domain and time domain;finally,the effectiveness of the control algorithm used is verified through experiments.Finally,summarize the related experiments of this system and the prospect of subsequent experimental work.
