Abstract:

In order to achieve superb precision tracking control of vibration output force,the corresponding controlalgorithm based on acceleration feedback is investigated.In this investigation,a vibration experiment device drivenby AC servo motor is designed,and a system dynamics model is established.On the Matlab /Simulink platform,thecontroller parameters are optimized by means of a real-coded adaptive genetic algorithm,and the sinusoidal outputforce tracking control is simulated.Finally,a vibration output force control system is built on the basis of the realtimecontrol software TwinCAT,and tracking experiments are carried out through the sinusoidal output force signalwith an amplitude of 50 N at the frequencies of 13.33,16.67 and 22.22Hz.Experimental results demonstrate thefeasibility of the vibration output force tracking control device and the effectiveness of the control algorithm.

Key words: vibration, force tracking control, acceleration feedback, genetic algorithm
