Answered What is the major difference among input signal and slider gain of the PID controller?

I am currently working on the simulation of my project to control a robot model of the step files which I exported from the SOLIDWORKS tool. I am facing an issue among the main difference between slider and signal gain. I have searched it on internet, however I noticed that most researchers are using sinusoidal wave signals to that of input of robot but other researchers have mentioned that the utilization of slider gain for the control of position. Can someone explain me this confusi

 

 

I want to the point answers. 
Thank You

    Hi

    The description which you have given is illustrating that you are looking fro the answer to the slider gain which is used for setting up the adjustable position of the robot through changing the position of slider while simulation is in running condition.

    However, having no idea of the details, the position of the slider is most probably because of the constant used for the simulations duration. The input block which is used for the generation of the sinusoidal wave is providing a time varying signal in sinusoidal form for the track of robot which is having a constant and predictable positions while the simulations are in progress.

    I hope you got answer to your problem.

    I think I got answer to your question.

    In my opinion it looks like slider and input signals are behaving in similar manner. Actually, you are having a closed look system having a PID controller on-board which is regulating the position of the robot in the same manner as input is changing which is reference signal in your case. The PID controller is requiring reference signal for the comparison of actual position of the robot and is then computed for controlling the action for correction of the error among actual position and desired position. Therefore the robot is following the position as indicated by the slider. This is a kind of same behavior as the manual input of the reference signal and is following the signal being inputted as the reference signal.

    Ping me in case of any issues.
