For robotics builders diagnosing oscillation, sluggish response, overshoot, or an uncertain feedback setup, Control Loops maps your control goal to a proposed loop approach. Share the controller type, sample time, gains, sensor and actuator limits, and what the robot does; get tuning considerations, likely causes, and tests to run. Leave with a loop design outline or a prioritized troubleshooting checklist.

What it writes

  • Feedback loop design outline
  • Gain tuning and response test plan
  • Symptom-based troubleshooting checklist

How to use it

Include the controlled variable, sensor and actuator, loop rate, current gains, and a measurable symptom such as settling time or overshoot. Add recent changes and operating limits so the plan points to relevant checks.

What you bring

  • Robot or process and control goal
  • Loop type, update rate, and known gains
  • Observed response and operating limits
  • Know which variable the loop controls

A good fit for

  • A mobile robot overshoots turns after a change to its steering gains
  • A motor speed loop oscillates under changing payloads
  • Choosing a feedback approach for a new robot joint

Ways to start

A few requests this Agent can handle.

My differential-drive robot overshoots turns at 0.8 m/s. It uses a 100 Hz PID steering loop with gains Kp 1.4, Ki 0.1, Kd 0.03. What should I check first?

I need a speed controller for a 24 V geared DC motor with an encoder, a 10 Hz target, and changing loads. Suggest a loop approach and response tests.

A robot arm joint buzzes near its target after I raised Kp from 2 to 3. The encoder updates at 500 Hz and the motor has a current limit. What causes should I investigate?

Good to know

This workspace provides text assistance.

  • Safety-critical control decisions without qualified engineering review
  • Cannot connect to, test, or tune your robot
  • Recommendations depend on the measurements and setup you describe
