system engineering and matlab
i need help with this problem. i attached the question and the block diagram too
consider the atenna control system block diagram, where motor, load and gears has a transfer function: G1(s)=0.25/s(s+1.5) the power amplifier is described. by 100/s+100 and the preampl. the design specifications are: ts<1.5s, %OS<1%, ess | step=0, ess | ramp <2% A) design a PID compensator to achieve the design specification. provide op-amp circuit realization for the compensator. B) design a rate feedback compensator to achieve the design specifications. verify your design by plotting the step and ramp responses. provide op-amp circuit realization for the compensator. C) which design would you recommend and why?
Ql. Consider the Antenna control system block diagram on p.273, where motor, load and gears has a
0.25 . . . 100
transfer function. G, (s) – s-(fl Ls)’ the power amplifier 15 described by s_+1oo’ and the preamplifier works
as a compensator. The design specifications are: ts < 1.55, %05 < 1%, esslsm, = 0, esslmmp < 2%.
a) Design a PID compensator to achieve the design specifications. Verify your design by plotting the
step and ramp responses. Provide op-amp circuit realization for the compensator.
b) Design a rate feedback compensator to achieve the design specifications. Verify the design by
plotting the step and ramp responses. Provide op-amp circuits for compensator realization.
c) Which design would you recommend and why?
