AI Technical Summary

Benefits of technology

The technology described for this purpose involves developing an improved system that uses two types of filters: one limited by their specific positions within it's own space (the moving platforms) while another works effectively beyond what was previously possible due to these limitations. This allows for more flexibility when designing motion simulation systems or other applications where accurate movement data cannot be achieved without sacrificing accuracy.

Problems solved by technology

In some cases where simulations on cars were developed, there may exist situations where users could feel unnatural due to having their platforms move around too much during certain stages of the experimentation. These scenarios include: (1) movement towards one end while other parts get close enough together; (2) lack of space between two components being worked upon simultaneously without interferring each others' motions - such as if they had just moved closer than usual but still needed to work properly. Additionally, even within specific areas near them, there might occur delays caused by factors like gravity or friction causing changes in how well the robot moves over time.

Embodiment Construction

[0015] A motion simulator may be any system with one to and including six degrees of freedom, where the degrees of freedom (DOF) can be x, y, z, pitch, roll, and yaw anyone. Preferably the motion simulator has six degrees of freedom. This note will illustrate the invention of a six degrees of freedom motion simulator. Those skilled in the art can easily understand how the present invention can be applied to a motion simulator with fewer degrees of freedom based on this description. figure 1 is a schematic diagram of an embodiment of a six-degree-of-freedom motion simulator, also known as a Stewart platform or a six-axis platform. The Stewart platform is well known and exemplified in the previously mentioned EP-A-446786 or US-A-2009 / 0047636. figure 1 The motion simulator shown includes a base 2 placed on the ground, and a platform 3 that moves relative to the base 2. For example, a cockpit with a seat can be installed on the platform 3 for users. The plinth may be a single f

Abstract

The invention relates to a motion simulator, which comprises a base, a platform which moves relative to the base and an actuator with controllable length, wherein the actuator is connected with the base and supports the platform, and the size of the base and the platform and the variable size of the actuator determine a movable operation area of the platform. The motion simulator also comprises a controller and a washout controller, wherein the controller is suitable for outputting motion cueing algorithm according to the required state, and the washout controller is provided with washout adaptation output. The washout controller converts a request platform state to a control platform state to maintain the platform stay in the operation area through the washout adaptation. The length of the actuator is controlled by the control platform state through the motion conversion, and the washout adaption is calculated by utilizing model prediction control algorithm.
