I'm little confused :( Is in't the same thing ? Lets say, 1. Angular Velocity = 10deg/sec 2. Convert it to radians/sec --> 10*(∏/180) 3. Now, calculate the angular frequency, f = ((10*∏)/180)/2∏ 4. If we see in the above equation, ∏ in the neumarator and ∏ in the denominator will be...

But, my input angular speed is in Deg/sec... so, you say, i convert that deg/sec to radian/sec and then use the formual f = ω/2∏ ??

Hi everyone, I need to calculate the Angular frequency based on the input angular speed. I'm thinking the formula would be Angular Speed, ω = 2∏f => Angular Frequency, f = ω/2∏ = ω/360° so, does the formula "f = ω/360°" will give me correct solution. Kindly guide me please.

@sophiecentaur Yes, it does have practical application. The sine, cos values (calculated using angular position) will be used by "function" to control the current input to the Motor in the EPS (Electronic Power Steering) ECU. As of now, I'm not quite sure what that "function" about.

@netgypsy I logged the data through CAN message from the real Car to get the Wheel Speed data. So, when I logged the data from the Car, I got around 10,000 samples of Wheel Speed Signal. And I import these values to excel sheet and at first trying to calculate Wheel position. And after...

After every 10ms, I need to estimate the current wheel position and then calculate the Sine, Cosine values for this angle. For example... - At first, I calculate the angular position (say for very 1st sample) and then calculate Sine,Cosine values for that angle. - And now, calculate the next...

Sorry about late reply (Due to Thanks Giving Holidays) And thank you for your suggestions. @sophiecentaur Yes, I reduced the two step process for calculating the angular position to 1 step as you suggested. And infact, the low dips in the input Wheel speed signal was due to my fault...

Hi, sophiecentaur I just did the integration of Angular speed only... As I said earlier, I receive the angular speed for every 10ms. So, after every 10ms, I need to find the current angular position of the wheel. Lets consider the below example with four samples of received wheel Speed...

Hi Nasu and Sophiecentaur Thank you for your inputs. @Nasu, I calculated the angular position using your inputs and simulated the graphs. Please check it in the attachment. @Sophiecentaur I think, I understand your point. The angular speed that I recorded is during random case...

Hi JHamm Thanks a lot for your reply. My angular speed input looks like something as shown in the attached figure, it is not constant. Right now, I'm thinking to do below steps to calculate the angular position Angular Position = (Current Speed Sample - Previous Speed Sample)*(Time...

FYI, the units for angular velocity that I receive is "deg/sec".

Dear All, After long time, I have to start working again on basic physics for my application in one of our automotive project. Anyway, my problem is, I receive the angular velocity of wheel from external source like (say CAN bus) for every 10ms, now, I need to calculate the Angular position...
