If step_time is set to a value that is too large, the system could exhibit oscillation or instability. If the controller input signal is very noisy or has a large quantization step size, the simple derivative estimation technique used in this code might not produce meaningful results for PD and PID controllers. In this situation, lowpass filtering should be used to smooth the input signal used in the derivative calculation. Alternatively, you might want to employ a more advanced control system design technique from Chapters 4, 5, or 6 instead of PID control.
An integral term eliminates steady-state errors in the plant response. The Ki gain of the integral term is usually set to a small value so that the steady-state error is gradually reduced. Setting Kd = 0 in the PID control algorithm of Eq. 1 produces the PI control algorithm shown in Eq. 4. With the correct choice of signs for Kp and Ki, a PI controller will generate an actuator command that attempts to drive the error to 0 with the proportional gain and removes any steady-state error with the integral gain.
Start by implementing a controller with the algorithm of Eq. 2 and choose a small value for Kp. A small value will minimize the possibility of excessive overshoot and oscillation. 2. Select an appropriate input signal such as a step input. Perform a test run by driving the controller and plant with that input signal. The result should be a sluggish response that slowly drives the error in the output toward zero. 3. Increase the value of Kp by a small amount and repeat the test. The speed of the response should increase.
