+// 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
