Precision Motion Base Software

High-Accuracy Motion Control and Coordinate Transformation for Advanced Simulation Systems

Servos & Simulation Precision Motion Base Software enhances motion system accuracy by correcting mechanical non-linearities and enabling advanced coordinate control of the moving platform.

Designed for high-performance applications, the software ensures precise motion behavior, accurate position tracking, and configurable coordinate reference points for specialized testing and simulation environments.

What Is Precision Motion Base Software?

Precision Motion Base Software compensates for non-linear mechanical behavior inherent in motion systems that use cranks and pushrods.

It also allows the coordinate system of the moving platform to be dynamically repositioned, enabling motion to be calculated and centered around arbitrary points in space rather than fixed mechanical geometry.

This significantly improves realism, accuracy, and flexibility in demanding simulation and testing scenarios.

Core Functionality

Non-Linearity Compensation

  • Removes mechanical non-linearities from crank and pushrod systems
  • Improves motion accuracy and repeatability
  • Ensures consistent system behavior across full motion range

Dynamic Coordinate System Control

  • Allows repositioning of the motion platform coordinate center
  • Supports offset-based motion calculations
  • Enables realistic motion behavior based on application needs

Example:

  • Coordinate center can be moved above the platform for aircraft pilot feel
  • Can be shifted forward (off the nose) for missile testing scenarios

Point Tracking in Free Space (Custom Capability)

  • Determines the position of specific points on a unit under test
  • Supports applications such as antenna or sensor testing
  • Provides spatial tracking beyond the platform reference point

Dynamic Software Evaluator

  • Reads feedback from actuator position sensors
  • Calculates:
    • Roll
    • Pitch
    • Yaw
    • X, Y, Z position
  • Provides real-time position data of the moving platform

Real-Time Position Reporting

Outputs platform position data to:

    • Local control computer
    • Host simulation system

Ensures operators always know the exact spatial position of the platform

High-Speed Processing

  • Internal iteration rate of 1 kHz
  • Supports host communication rates from 200 Hz up to 1 kHz
  • Enables precise, responsive motion control

Integration Options

Precision Motion Base Software can operate on:

  • The motion base control computer
  • A customer-provided host computer

This allows flexible system integration depending on application requirements and architecture.

Performance Requirements

For optimal performance, the motion system must include:

  • Backlash compensation in gearmotors
  • High-bandwidth drive amplifiers

These mechanical and electrical characteristics are required to fully support the software’s precision capabilities.

Why It Matters

Mechanical motion systems inherently introduce non-linear behavior and positional limitations.

Precision Motion Base Software ensures:

  • Accurate motion regardless of mechanical geometry
  • Flexible coordinate positioning for specialized applications
  • Real-time awareness of platform position

This is critical for applications requiring high precision, repeatability, and spatial accuracy.

FAQ

Precision Motion Base Software improves motion system accuracy by removing mechanical non-linearities and enabling advanced control of the platform’s coordinate system.

Non-linearities are mechanical inconsistencies caused by components such as cranks and pushrods, where motion output does not directly match input. The software compensates for these effects to ensure accurate motion.

It allows the center of motion calculations to be moved to a different point in space, such as above or ahead of the platform, improving realism or supporting specialized testing applications.

Yes. The software calculates roll, pitch, yaw, and X, Y, Z position continuously using feedback from the actuators, allowing precise tracking of the moving platform.

The software operates at an internal iteration rate of up to 1 kHz, with host systems able to communicate at rates from approximately 200 Hz to 1 kHz.

Yes. The motion system must include appropriate backlash control and sufficient bandwidth in the gearmotors and drive amplifiers to fully achieve the software’s precision capabilities.
