Now, we can **get a precise definition of SSE** in this system. Sign in to add this to Watch Later Add to Loading playlists... Assume a unit step input. Your grade is: Problem P1 For a proportional gain, Kp = 9, what is the value of the steady state error? get redirected here

The output is measured with a sensor. Your grade is: When you do the problems above, you should see that the system responds with better accuracy for higher gain. Enter your answer in the box below, then click the button to submit your answer. Your cache administrator is webmaster.

Try several gains and compare results. In our system, we note the following: The input is often the desired output. In this lesson, we will examine steady state error - SSE - in closed loop control systems. The actuator is a valve, represented here by a constant transfer function (Kvlv).

In fact Also, So Thus This shows that there is a residual error, as was discussed at the first of this lecture. Steady State Error Matlab Brian Douglas 96,450 views **13:54 Intro to** Control - 11.4 Steady State Error with the Final Value Theorem - Duration: 6:32.

You can set the gain in the text box and click the red button, or you can increase or decrease the gain by 5% using the green buttons. You will get a grade on a 0 (completely wrong) to 100 (perfectly accurate answer) scale. If we have a step that has another size, we can still use this calculation to determine the error.

There is a controller with a transfer function Kp(s). The difference between the input - the desired response - and the output - the actual response is referred to as the error.

There is a sensor with a transfer function Ks. Steady State Error Solved Example Please try again later.

The system returned: (22) Invalid argument The remote host or network may be down. Next Page Skip navigation UploadSign inSearch Loading... If there is no pole at the origin, then add one in the controller. this page That is especially true in computer controlled systems where the output value - an analog signal - is converted into a digital representation, and the processing - to generate the error,

You should see that the system responds faster for higher gain, and that it responds with better accuracy for higher gain. You will have reinvented integral control, but that's OK because there is no patent on integral control.
