PID output is the same at every call?

[aaprasad]

Hi, I'm not sure if this is expected behavior but when I try running the PID controller with different inputs at each call it outputs the same value every time regardless of what gains I choose

for instance if I run

pid = PID(1, 0.5, 0.01, setpoint=1)
for _ in range(10):
    print(pid(np.random.normal()))

It will print the same value each time but my understanding is this should change no?
