Stewart platform, being 6DoF parallel mechanisms, have a coupled dynamics.

In order to ease the control design, decoupling is generally required.

Several approaches can be used (Section <a href="sec:control_decoupling">sec:control_decoupling</a>).

<blockquote>
|
||
<p>
|
||
In general, force sensors such as load cells, work well to measure vibration, but have difficulty with cross-axis dynamics.
|
||
Inertial sensors, on the other hand, do not have this cross-axis limitation, but are usually more sensitive to payload and base dynamics and are more difficult to control due to the non-collocated nature of the sensor and actuator.
|
||
Force sensors typically work well because they are not as sensitive to payload and base dynamics, but are limited in performance by a low-frequency zero pair resulting from the cross-axial stiffness.
|
||
This zero pair has confused many researchers because it is very sensitive, occasionally becoming non-minimum phase.
|
||
The zero pair is the current limitation in performance using load cell sensors.

</p>
|
||
<blockquote>
|
||
<p>
|
||
On the other hand, the traditional modal decoupled control strategy cannot deal with the flexible Stewart platform governed by Eq. (34) because it is impossible to achieve simultaneous diagonalization of the mass, damping and stiffness matrices.
|
||
To make the six-DOF system decoupled into six single-DOF isolators, we design a new controller based on the leg’s force and position feedback.
|
||
The idea is to synthesize the control force that can compensate the parasitic bending and torsional torques of the flexible joints and simultaneously achieve diagonalization of the matrices M, C and K.
