Mathematical model of fast hydraulic actuator dynamics, based on Riemann’s
equations, is presented in the paper. Fast hydraulic actuator can be assumed as two serially
connected compressible fluid flows controlled by supply and return variable flow restrictors
enclosed in control servo-valve and separated by actuator piston. Exhibited dynamic model
includes several physical effects, such as: fluid viscosity and compressibility, compression and
expansion, wave propagation, actuator equivalent inertia, potential external load and arbitrary
servo-valve control input. Solution of the presented mathematical model is evaluated by using the
method of characteristics. Corresponding boundary conditions assume the actuator piston position
as a movable boundary between the direct and the reverse part of the actuator chamber.
