Beyond PID – Frequency Domain Strategies for High Throughput Motion

Whether your goal is sub-micron precision or maximizing parts-per-hour, the bottleneck is the same: the system’s mechanical limits and the impact of environmental disturbances. Traditional time-domain tuning often leaves performance on the table or results in systems that are sensitive to minor process disturbances.

This webinar demonstrates how frequency domain analysis – once reserved for academia – is now a practical necessity for the modern machine builder. We will show how to use Bode and Sensitivity analysis to “see through” mechanical resonances and stabilize loops for maximum throughput. We will also address how advanced digital filter architectures and power electronics impact your machine’s dynamic stiffness. By moving beyond standard PID, you can build machines that are faster, quieter and more robust against real-world disturbances.

Learning Objectives:

• Diagnose mechanical bottlenecks – Use frequency response (Bode) tools to identify exactly where mechanical resonances are limiting your machine’s speed
• Increase dynamic stiffness – Learn how loop shaping and notch filters allow for higher gains, leading to better disturbance rejection and faster settling
• Future-proof your tuning – Understand why stability margins (Gain/Phase) are the key to machines that stay in-spec as hardware ages
• Eliminate sluggish moves – Identify how PWM gain loss and friction affect cycle times and how to neutralize them with advanced drive features
