Adjusting PID Gains
An earlier discussion explained PID and showed the Bode diagram (open loop gain as a function of frequency)for it. A number of users of PID have indicated that they have difficulty adjusting the gains (KP for theproportional gain, KI for the integral gain, and KD for the differential gain). This reminds me of the golfer onthe first tee whose first three swings resulted in nothing but air and whose fourth swing dribbled down the
fairway. He turned to his friends and said, "This is a difficult course, isn't it?" It was only difficult because he
didn't understand the basics and hadn't practiced them.

This discussion will concentrate on the basics - what happens when you adjust each of the three factors? It willstill take some practice to do it well and quickly - and you may never become a 300 yard hitter, but your scorewill improve dramatically!

Two Bode diagrams from the earlier discussion will be used to help gain a picture of what happens when eachof the factors is adjusted. The first Bode plot to be used is of the PID network by itself. Later, a Bode diagramof the total loop gain incorporating the motor (which is also an integrator) will be shown.

The PID network is shown below illustrating the effect of changing only the proportional factor (KP). As can
be seen, increasing KP not only increases the mid-frequency range proportional factor, but also lowers the
frequency at which the integration factor ceases effectiveness and raises the frequency at which the differentialfactor begins to kick in. The effect of lowering KP is also illustrated.

 

 

5-Wire Motor
This style is common in smaller unipolar motors. All of the common coil wires are tied together internally abd brought out as a 5th wire. This motor can only be driven as a unipolar motor.

 

 

 

6-Wire Motor
This motor only joins the common wires of 2 paired phases. These two wires can be joined to create a 5-
wire unipolar motor. Or you just can ignore them and treat it like a bipolar motor!

 

 

 

8-Wire Motor
The 8-wire unipolar is the most versatile motor of all. It can be driven in several ways:
4-phase unipolar - All the common wires are connected together - just like a 5-wire motor.
2-phase series bipolar - The phases are connected in series - just like a 6-wire motor.
2-phase parallel bipolar - The phases are connected in parallel. This results in half the resistance and inductance - but requires twice the current to drive. The advantage of this wiring is higher torque and top speed.
