简单的PID控制python代码

好的，以下是简单的PID控制的Python代码：

# define PID parameters
Kp = 0.5
Ki = 0.1
Kd = 0.2

# define initial error and integral
error = 0
integral = 0

# PID loop
while True:
    # measure system output
    output = measure_output()
    
    # calculate error
    error = setpoint - output
    
    # calculate integral
    integral = integral + error
    
    # calculate derivative
    derivative = error - prev_error
    
    # calculate control variable
    control_variable = Kp*error + Ki*integral + Kd*derivative
    
    # update previous error
    prev_error = error
    
    # apply control variable to system input
    apply_control(control_variable)

希望这能帮到你！还有什么问题可以问我哦~
