Subgrade bears both the weight of superstructures and the impacts of running trains.
Its stability affects the line smoothness directly, but in situ testing method on it is inadequate.
This paper presents a railway roadbed in situ testing device, the key component of which is an excitation hydraulic servo cylinder that can output the static pressure and dynamic pressure simultaneously to simulate the force of the trains to the subgrade.
The principle of the excitation system is briefly introduced, and the transfer function of the closed-loop force control system is derived and simulated; that, it shows without control algorithm, the dynamic response is very low and the following performance is quite poor.
So, the improved adaptive model following control (AMFC) algorithm based on direct state method is adopted.
Then, control block diagram is built and simulated with the input of different waveforms and frequencies.
The simulation results show that the system has been greatly improved; the output waveform can follow the input signal much better except for a little distortion when the signal varies severely.
And the following performance becomes even better as the load stiffness increases.
