This paper is complementary to Part 1, [1], submitted in the present conference and deals with the dynamic behavior of an aircraft (three-wheeled heavy vehicle) during taxing. An electro-hydraulic servo valve EHSV with a PI controller is modeled and incorporated into the hydraulic power steering system as an equivalent replacement to the directional control
valve assembly presented in Part 1. The design parameters values of EHSV are tuned to give similar response to that of DCV assembly. Moreover, the steering hydraulic system is integrated into a complete vehicle handling model using MATLAB-SIMULINK to assess the dynamic behavior of the vehicle under various designs and operating conditions. The transient and steady state responses of the vehicle are examined.
