The system block diagram for position control of a satellite is given below. Block
Explanations of the information on the diagram and values, if any, are stated next to the figure.
J = 10 satellite inertia (N.m.s2 /rad)
8, : satellite position reference information (rad)
:satellite position current information(rad)
Hy=1,H,=1
W : disruptive torque input (Nm)
a) If proportional (P) control is used in the system, determine the value range (Dc (s) = kp) that is kept constant in the system.
b) If PD control is used in the system (Dc(s)=kp+ kpS), find the system type and the error structures that may occur when only the reference input is active.
c if PD control is used in the system (Dc(s)=kp+kpS),find the system type and the error
structures that may occur when only the input is active
d) If PI control is used in the system (Dc (s)= kp+ (k/s), find the system type and the error structures that may occur when only the reference input is active.
e) If PI control is used in the system (Dc (s) = kp + (k/s)), find the system type and the error structures that may occur when only the blocking input is active.
f if PID control is used in the system (Dc(s)=kp+(k/s+kpS) only the reference input is active.
Find the system type in the situation and the error structure that may occur.
g)If PID control is used in the system (Dc(s)=kp+ (k/s+ kpS only blocking is active.
Find the system type in the situation and the error structure that may occur.
