I'm converting a continuous transfer function into a discrete one, using 'c2d' cmd.
But realised that different sampling frequency / discretized step time would effect system stability.
The transfer function I'm working on is a 9th order system.
dt = 1/7993 can offer a stable discrete system while dt = 1/7993/226 would result in an unstable system.
Therefore, I'm wondering what the upbound limit for sampling frequency for c2d is.
And is there any other way that I can get a discrete system using dt = 1/7993/226 or even higher sampling rate?
