【Abstract】 An adaptive compensation method was presented to improve the precision of the long weighbridge weight-in-motion system.According to the two degrees of freedom weight-in-motion model,the compensation filter was designed using a zero-pole points eliminating method.The output signal was put into the filter to improve the response characteristic and the signal was made steady quickly.The simulation indicates that the method can reduce the oscillation time and improve the precision efficiently.The method also has a good adaptability.更多还原
