Algorithms

Architectures for Economical Motion

Motion-control costs have more to do with what’s needed to hook up components than with the motor and controller.

factors contributing to the drive instability
The case of the unstable servo
1

Several factors can contribute to the likelihood of an ac drive experiencing instability.

Autotuning algorithms for servos
Inside auto tuning algorithms for servos

Today, autotuning has improved and the best autotuners are better at tuning than are most people.

Hybrid Motion Technology Steppers
Hybrid Motion Technology

Hybrid Motion Technology combines step motors with servo control technology to offer the best from both worlds. Paul Kling from IMS Schneider Electric Motion demonstrates the technology to Ken Korane of MACHINE DESIGN. 8:45

Designing Positioning Systems for Constant Velocity

A few mathematical tools can help guide the way toward defeating wobble, jitter, cogging, and similar effects that can prevent positioning systems from working smoothly

Vibration suppression demonstration

Scott Carlberg demonstrates Yaskawa's vibration suppression algorithm used in its motor drive systems to Lee Teschler of MACHINE DESIGN.  3:39

New Algorithm Thwarts Velocity Disturbances in Motion-Control Schemes
1

A new control methods cuts velocity disturbances to keep motion profiles smooth and precise.

Motion Reference Guide: Software Keeps Linear-Stage Integration Straight

Software integration presented additional challenges. Complex application routines and custom configuration of individual components turned programming and debugging into a protracted and painstaking trial-and-error process

Mechatronics Q & A: When is it OK to break mismatch rules?

Q: I design servocontouring applications using both linear motor and rotary/ball-screw methods, and the inertia mismatch issue has always been a concern for me.

Mechantronics Q & A: Hold It Steady

Q: What is the difference between sizing a load for static versus dynamic holding?

Model-based design for mechatronics systems

It is now practical to write software for real-time systems long before the actual computer hardware is sitting in a physical prototype.

Simulating for Mechatronics

Modern simulation software lets engineers spot electromechanical problems long before they get to the stage of real hardware.

Correcting errors that never happen

The Luenberg Observer lets motion-control systems mathematically predict and cancel position errors before they happen.

Smooth rotation

An adaptive algorithm kills jerky motions in motors.

When to go Linear

Optical or magnetic linear encoders handle high-res needs in dirty jobs.
