Abstract:A resonant frequency and resonant amplitude model presents based on the loader analyses of the resonant part of Resonant Cement Pavement Breaking Vehicle (RCPBV). The mathematical model of the frequency control based on proportional pump-controlled-motor system is established with regard to the nonlinear and parameter uncertainties of Electro-hydraulic system of the machine firstly, the backstepping sliding mode control algorithm is designed, the adaptive controlling law for parameters uncertainties is given to ensure the asymptotic convergence of resonant frequency tracking based on the Lyapunov function. Simulation and experimental on vehicle results show that the method meets the controlling requirements of cement pavement breaker with better Frequency tracking performance.
