Compensator Definition and 16 Threads

Hello Community, for a School Projekt I must design a lag compensator according to Ogata. Unfortenutely I have some Problems. At first I must find a Value for Kv. I don't know why he use for Kv 5 1/sec in this example. He don't explain why he use 5 and why he use at least 40 degrees. In the...

Homework Statement Homework Equations For lag compensator pole is dominating For lead compensator zero is dominating The Attempt at a Solution So for lag compensator: P1 is closer to origin than Z1, so mod of P1 < mod of Z1 So P1 > Z1 (since the poles and zeroes are negative) And for lead...

Homework Statement [/B]Homework Equations I used voltage divider rule. The Attempt at a Solution I get value of a = 3 Book answer is 1.5. Is book wrong or am I wrong?

Hello, in my final project for System Control i have been stuck for some time on this following task What i cannot figure out is how to make all these condition work at the same time. When I tried designing a PD controller in sisotool or MATLAB for the i and ii part it worked but i couldn't...

Homework Statement Homework EquationsThe Attempt at a Solution For the above modeled transfer function of the plant, I'm trying to design a compensator that satisfies some requirements. a. The maximum control bandwidth (0 dB crossover frequency) is 100 rad/s. b. The minimum phase...

Homework Statement What is the effect on the phase and gain margins of a system when a Phase Lead Controller/Compensator is added? Homework Equations I have designed the phase lead controller for the system so if anyone wants to see it, please ask The Attempt at a Solution I know, that in...

Homework Statement I was just wondering what was the general effect on phase and gain margins when a phase lead compensator was is added to a system. Homework EquationsThe Attempt at a Solution

I'm trying to design a lead compensator for a double integrator plant, which is plant = tf([1],[1 0 0]) I started with the angle condition. So, poles contribute (+) angle and zeros contribute (-) angle and that sums to 180 Desired pole location is 4.4 +- 4.4j So, 45 + 45 = 90 degrees comes...

all these things that we learn in control systems...how are they applied in practical situations? for example, we design compensators using bode plot or root locus and we get its transfer function. After that how is the compensator realized??

My professor in Feedback Control Systems told me that a lead-lag compensator is basically a low pass filter and that you can't amplify high frequencies because it requires a lot of energy. Thus, you can't design a PID/lead-lag compensated transfer function which acts like a bandpass filter. Is...

Hi All, I'm working on my final year project on synchronous buck converter (SBC). In this project, i have to use an adaptive gate drive (AGD) and a compensator to switch on both of the SBC switches. The AGD is connected to the second switch (Low side switch) of the converter meanwhile for the...

Hi everyone, I would please like some suggestions regarding where my error is, designing a lead compensator with the root locus method for a unity feedback control system where G = [12.5] / [2.5 1 2500]. I want to set the overshoot zeta = 0.5 for an overshoot of 16%, and settling time Ts =...

Hi, I am having difficulty understanding how to convert pole and zero locations of a lead lag compensator into lead and lag time and vise versa. I have a digital lead and lag compensator which requests: gain, lead time (min) and lag time (min). However i have the gain zeros and poles of...

I have learned from some source that there is a device called neutral compensator .Iwould like to know about it in detail.

Hey, Anyone know where I might be able to get a thermocouple voltage compensator (an electrical "ice bath" circuit) for cheap or if I may be able to make one? For a T and/or K type thermocouple. I am looking in the range of $30 or less. Here is a description of what I'm talking about. Just...

Hi Given an open loop non-minimum phase transfer function, what in general are the approaches preferable to design a compensator for it? Suppose one is given the location of the desired closed loop poles, is it a standard practice to use complementary root locus (or negative root locus) for...
