Play with Program 28-12 to see how the distance moved and the speed of the move affect the motion we get. Think about how to design an algorithm that ties the gain to the distance to be moved and the speed to get smooth startups and stops. The main thing to notice is that the speed is always a function of the gain, and if you amplify the gain value, the motor gets the move done faster. A relationship exists between the time and the gain multiplier, and how we manage it determines the accuracy of the move timing. In this program, we are satisfied if the move gets to within two counts of its destination, as determined in the SetMotorPower method. Change that to zero count and see what happens. How does the speed of the move affect this requirement What can we do to the speed to make this work better at the tail end of each move Remember, there is no ramp up or ramp down in this program; it s all in how the gain is controlled based on the distance to be moved. (This is a kind of ramp control, but not the managed movement we would need for a complicated coordinated move.)
