Experimental research on dynamic performances of 2-dimensional force sensor applied for force feedback magnetic levitation control system

Dynamic performances of 2-dimensional force sensor is a deciding factor of electromechanical coupling system, therefore, it is necessary to study its dynamic performance in the experiment. Dynamic model of mechanical structure is established and its pulse incentive response curves are obtained through the simulation. Dynamic performances of mechanical structure of 2-dimensional force sensor are studied in the experiment by using impulse stimulation method and its experimental values of pulse incentive response of are got. comparing experimental values with the theoretical values, the results show that the special structure design can effectively reduce the cross error; because of electromechanical system existing coupling, the performances of electromechanical coupling system are poorer and its error is larger, so adjusting circuit parameters and modifying dynamic performances, relative square integral absolute error, peak error and cross error of mechanical structure modified reduce greatly and amendment reduces the error of the measurement circuit and mechanical structure coupling.
