Traditional classical (DC) servo systems exhibit typical controller oscillation up to a few encoder counts. Let me emphasize the word relatively. The noise level is at approximately 3 nm (peak-peak, 10 kHz sample frequency, unfiltered) which can be attributed to the interferometer and environment during the time of the measurements. Hexapod positioners are often referred to as Stewart Platforms. The resolution of a stepper motor is the number of degrees it rotates per step (degrees/step). Advanced controllers can interpolate thousands of microsteps between each full step to achieve higher resolution. The Stepper Motor offers a better bottom line for your budget and are inexpensive when compared to Servo Motor motion control systems for their better suited applications when considering lower acceleration and high holding torque requirements.

We hope the PI blog is an enjoyable and informative resource, and a starting-point for innovation across disciplines. A typical servo system feeds off errors, i.e., it needs to see an error before it reacts. Why is it impossible to measure position and momentum at the same time with arbitrary precision? SMC controllers suppress high frequencies and still allow dynamic positioning with minimal overshoot, eliminating oscillations and side effects for the overall system stability. PI offers the broadest and deepest range of precision motion technologies for micro and nano precision applications. Answer: c. Explanation: Pulse per second is mathematically given as PPS = (Rpm/60)*(number of steps per minute).
