Study on dynamic characteristics and experimental methods of mechanical resonance system experimental platform
In order to improve the teaching effect of automatic control principle and other similar courses,and promote the construction of integrated courses,a mechanical resonance system experimental platform was developed.Firstly,the mathematical model of the experimental system was established,the nonlinear dynamic characteristics of the proposed mechanical resonance system were analyzed in detail,and the L2 stability and Lyapunov stability of the experimental system were discussed.Secondly,the software and hardware components of the experimental platform and its practical application methods were introduced.Finally,the mechanical resonance system experimental platform was verified by simulation and physical experiments.The results show that the time domain characteristics,frequency characteristics of the second-order system and the performances of the stabilizing control based on PID,LQR or the Lyapunov function can be intuitively displayed by using the experimental platform.The mechanical resonance system experimental platform can better assist in completing the teaching task of the courses related to control engineering,and can provide technical support for the scientific research activities of the control engineering.
