• In tracking controllers we assume that the setpoint will be moving. As a result we will focus on a desired error function, instead of an overall transfer function.
• To do this we must first develop a function that relates the elements of the control loop, to the desired error response,
• Specific controllers can be developed using the relationships used for the positioning controllers.
• As an example tracking control would be needed in your hand for curved letters, positioning would result in block letters.
