6.7.2.3 Bode
Select ph+gain in Loop constructor window to simulate and analyze the frequency responses of
velocity controller (Vel controller), velocity open loop (Vel open loop), velocity closed loop (Vel close loop),
position controller (Pos controller), position open loop (Pos open loop) and position closed loop (Pos
close loop). Check the checkbox of the desired item to simulate and analyze its Bode plot. The above six
items can be simulated and analyzed at the same time. Click on the curve to display frequency response
value to analyze control system.
(1) Vel controller (Velocity controller): Frequency response of velocity controller
(2) Vel open loop (Velocity open loop): Frequency response of velocity open loop
(3) Vel closed loop (Velocity close loop): Frequency response of velocity closed loop
(4) Pos controller (Position controller): Frequency response of position controller
(5) Pos open loop (Position open loop): Frequency response of position open loop
(6) Pos closed loop (Position close loop): Frequency response of position closed loop
