sample_system(sysc, Ts, method='zoh', alpha=None, prewarp_frequency=None)¶
Convert a continuous time system to discrete time
Creates a discrete time system from a continuous time system by sampling. Multiple methods of conversion are supported.
sysc (linsys) – Continuous time system to be converted
Ts (real) – Sampling period
method (string) – Method to use for conversion: ‘matched’, ‘tustin’, ‘zoh’ (default)
prewarp_frequency (float within [0, infinity)) – The frequency [rad/s] at which to match with the input continuous- time system’s magnitude and phase
sysd – Discrete time system, with sampling rate Ts
- Return type
See TransferFunction.sample and StateSpace.sample for further details.
