I have a open loop TF given by 2s+100/s^2. As stated in theory, type 2 system should provide zero steady state error for velocity inputs. Could any body explain the limiting factor of this velocity. I mean, what is the maximum velocity input that this system can track?
I was going through SICK absolute encoder . Referring to page No 7, timing diagram depicts that for 30 bits resolution, 33 clock pulses needs to be sent to retrieve position information. Is that right?
gm is the slope d(Id)/d(Vgs). Look at the basic ID-VG curve and you can see that there's a slope that's maximum and consistent, in the subthreshold region (thus maximizing gm) and it rolls over as the FET goes into strong saturation. This has not to do with short channel per se. Short channel brings you some non-classical device features (lik
Those probes should be suitable. It isn't a high performance machine I'm afraid but it will be fine for hobby usage. Don't forget to calibrate the new probes before you take any measurements: 1. set their switches to X10 position 2. connect the probe to the calibration output on the scope and ground clip nearby 3. adjust the Y gain to get a wavefor
After a frantic search to realize sine/cosine functions in analog, I came across the patent reference . Can anybody explain , how the linear approximation was arrived? (refer page 10)
I have two waveforms, A and B of identical frequency. "A" is the reference wave which is fixed, "B" wave moves in steps of 5us- 20ms. All I need is to track the change in phase without recomputing every time. Can anybody suggest proven method in hardware
Dear friends, I am trying to design a floded cascode OTA for the sample and hold circuit that should work with sampling frequency of 5 MHz, this requires me to have an OTA with a typical GBW of 100 MHz. I am using 0.35 um CMOS technology with channel length I st for all the transistors to 1 um. The problem I am finding it very difficuilt to a
Dear Experts, Hi in "Radiation" example "radex15", the profile of SEU track charge versus time was plotted. I want to plot SEU charge track versus position (for example x). could you please help me? thanks
Hi this is my attempt to create a cheap but effective 1-60MHz measurement marker generator and simple tracking generator for a Tektronix 491 vintage spectrum analyzer. The nominal levels of the input of the analyzer are shown in the right. Calibration, a must for old machines, should be of no importance with my plugin, since the DDS generated mar
In the circuit, I want to compare the voltage reference Vref and source voltage Vdd. It is necessary to make Vref change with Vdd, which means a constant voltage is supposed to connect between this two voltage. But I have no idea what structure can achieve this.
I was looking at affordable yet a good quality spectrum analyzer with tracking generator that can perform in 0.4 - 6.0 GHz range and has a decent ability to produce reports and graphs. After a targeted search I discovered the following products from SignalHound company ( ) - SA124B spectrum analyzer with matching SG124A tracki
Hi, i am trying to simulate the mutual inductance of 3D spiral coils for wireless power transfer application. While simulating the coil terminals with lumped port following warning occurs "User Defined Primitive: End edge position: User Defined Primitive: Point0: x = 10.2109956554404, y = 0.00127102124808265, z = 0.5 Adaptive solution
The idea behind your examples seems to be that the sampled data should look the same as time continuous data. That's not the way time discrete systems are designed. You need to sample the shaft position only at the calculated high speed if it can take arbitrary positions at each sample (being moved with infinite torque). But the real system has
Hello, Here is my PCB file. I need to know why P1_1 and U2_1 don't move by changing their room position. In addition by selecting all components again, they don't move.(ROOM name :TCP1) Thank you.
Each model of representation of a physical phenomen is appropriate to the school level in question. For example, quoting the Poynting vector makes sense only when the student is familiar with the Maxwell's equations in differential form, which postulates that varying one field generates another field, and vice versa, even since being the pointing v
In general interupts are not used with QEI registers, but rather with Timers; we want to take the current position at fixed intervals and then calculate the speed or just check whether certain position were reached or not.
A general solution that doesn't depend on a specific camera position and lens properties would be a calibration grid placed on the playground. Then determine a mapping function (e.g. 2-D look-up table) that calculates x-y coordinates for pixel positions.
Hello, In this picture I can't find the X position of pins of 1,3,5,7. I will thankful if you could help me. HanRUn911105A 155815
Your videos are visible now. Your mechanism looks like the sort of thing that might have a cam or gear with a notch in it. If it doesn't stop after a cycle, it skips the notch and continues for a second cycle. The natural question to ask: What makes your motor start a cycle, and what makes it stop? Measurements are precise with a microswith. It
I'd like to share some experience about PCB layout. The usual order in which components are placed on a printed circuit board: Place components in a fixed position that closely match the structure, such as power sockets, indicators, switches, connectors, etc. After these devices are placed, they are locked by the LOCK function of the software
