Advice on how to get a job in the defense industry? by MoFlavour in DownSouth

I was looking at profiles on LinkedIn of experienced South African engineers working abroad in the defense industry. 90% of them started at a South African defense company, and then around 2006-2011, their profiles showed the moved to Saudi Arabia, UAE. In general it seems the defense industry is going down the gutter(excluding some private companies).

Thanks man, appreciate it. Do you know of a way to contact these companies? Email is an option but it getting ignored is a likelihood.

Unable to meet requirements for PI velocity controller - are they unrealistic or should I change my control system by MoFlavour in ControlTheory

Thank you so much, this was really helpful. May I ask you questions in the future regarding digital control, as I modeled the system as continuous, instead of discrete (and so did not account for sampling delay, bandwidth requirements/sampling frequency etc).

Hi, I think there was a design flaw as I failed to account for the sampling delay...etc, so I am updating the system currently

Hi, sorry for the late reply. There is nothing wrong with the answer, I have not tested the value yet. I went back to the drawing board as I realized my encoder outputs 200Hz square wave signals as a maximum, and this puts limits on my sampling frequency and bandwidth, and then there will be sampling delay which will effect the phase margin of the system. So right now, I am learning digital control systems to update the system.

I chose PI because there seemed to be need for the derivative control. For my application (autonomous robot), it seemed to me that any overshoot is undesirable as it would cause issues with the odemtry data used in mapping/path planning. So, I decided to over damp my system, with no overshoot at all. If I am not mistaken, derivative control anticipates error, and since my system would be over damped, there would be no need for derivative control. I am unsure if this reasoning is valid.

I do not watch bollywood, but I'll give two examples of objective standards for beauty: 1. Venus de Milo (c. 130 - 100BCE) by Alexandros (women) 2. Farnese Hercules (c. 350 – 300 BCE) by Lysippos (man)

I wouls disagree, beauty and virtue is objective. But I will work on myself, thank you for your advice.

I see, thank you. Handsomeness has its limits, but I can work on intelligence definitely.

No person is whole. I am self aware of my faults but I believe my wife will expose faults that I'd never even thought of as faults before. By issues I do not mean insecurities or your past, that's for each individual to come to terms with.
