pid algorithm in python code example

Example: python pid control

from simple_pid import PID
pid = PID(1, 0.1, 0.05, setpoint=1)

# assume we have a system we want to control in controlled_system
v = controlled_system.update(0)

while True:
    # compute new ouput from the PID according to the systems current value
    control = pid(v)

    # feed the PID output to the system and get its current value
    v = controlled_system.update(control)
