PID has been much more common in process control where temperatures, pressures, etc. need to be
optimally controlled. The primary benefit from the Integral term is the reduction of steady state error while
the Differential term helps improve the responsiveness and stability. The theory is valid whether one is
controlling temperature, pressure or position. A big difference between a typical process closed loop and a
typical position closed loop is the dynamics or frequency response. It is not unusual for a positioning servo
to have a bandwidth of 10 Hz or for a process loop to have a bandwidth of 0.1 Hz. Control of temperature,
pressure, etc. is usually a "slower" process than positioning with motors.

What are their limitations?
Low Efficiency – Unlike DC motors, stepper motor current consumption is independent of load. They draw themost current when they are doing no work at all. Because of this, they tend to run hot.
Limited High Speed Torque - In general, stepper motors have less torque at high speeds than at low speeds.
Some steppers are optimized for better high-speed performance, but they need to be paired with an
appropriate driver to achieve that performance.
No Feedback – Unlike servo motors, most steppers do not have integral feedback for position. Although greatprecision can be achieved running ‘open loop’. Limit switches or ‘home’ detectors are typically required forsafety and/or to establish a reference position.

A stepper motor is an electromechanical device which converts electrical pulses into discrete mechanical movements. The shaft or spindle of a stepper motor rotates in discrete step increments when electrical
command pulses are applied to it in the proper sequence. The motors rotation has several direct relationships to these applied input pulses. The sequence of the applied pulses is directly related to the direction of motor shafts rotation. The speed of the motor shafts rotation is directly related to the frequency of the input pulses and the length of rotation is directly related to the number of input pulses applied.

Stepper Motor Advantagesand Disadvantages
Advantages
1. The rotation angle of the motor is proportional to the input pulse.
2. The motor has full torque at standstill (if the windings are energized)
3. Precise positioning and repeatability of movement since good stepper motors have an accuracy of
3 – 5% of a step and this error is non cumulative from one step to the next.
4. Excellent response to starting/ stopping/reversing.
5. Very reliable since there are no contact brushes in the motor. Therefore the life of the motor is simply dependant on the life of the bearing.
6. The motors response to digital input pulses provides open-loop control, making the motor simpler
and less costly to control.
7. It is possible to achieve very low speed synchronous rotation with a load that is directly coupled to the
shaft.
8. A wide range of rotational speeds can be realized as the speed is proportional to the frequency of the
input pulses.
