// Aim:To determine the system accuracy of electrohydraulic servo system
// Given:
// servo valve gain:
G_SV=0.15; //(in^3/s)/mA
// cylinder gain:
G_cyl=0.20; //in/in^3
// feedback transducer gain:
H=4; //V/in
// weight of load:
W=1000; //lb
// mass of load:
M=2.59; //lb.(s^2)/in
// volume of oil under compression:
V=50; //in^3
// system deadband:
SD=4; //mA
// bulk modulus of oil:
beta1=175000; //lb/in^2
// cylinder piston area:
A=5; //in^2
