x=-d^2x/dt^2-dx/dt+U
Q1=Kv w x sqrt(Ps/2+sgn( x) (Ps/2-P1)
Q2=-Kv w x sqrt(Ps/2+sgn (x) (P2-Ps/2)
ိdP1/dt=B/(A *xp+V) (Q1-A*Vp)
ိdP2/dt=B/(A(L -xp)+V) (Q1-A*Vp)
m dVp/dt =A(P1-P2)
xp=displacement of actuator
Vp=velocity of actuator
A=anulus area of piston
L=actuator stroke
U=current
x=servovalve displacement

These equations are servohydraulic mechanism.
Is there anyone who can solve these equations to build model by using matlab and simulink.Please help me because i am a beginner to study matlab and i am facing ploblems when try to solve it.

dear there are some methods avail able in MATLAB to solve differential equations please study following examples and demo of MATLAB
odeexamples,
odedemo
ode45
etc
