Motion Master Product Line
The Motion Master product line is a 6 degree of freedom (DOF) sensor with 3 angular rate gyroscopes and 3 linear accelerometers. The angular rate sensors appear to be MEMs gyros with a vibrating proof mass. The linear accelerometers are piezo technology.
The rate gyros of the Motion Master line have bandwidths of 40 Hz with angular rate saturation points ranging from 1200 to 150 deg/sec (21 to 2.6 rad/sec). The accelerometers are rated from 2 to 500 g with bandwidths ranging from 250 to 2400 Hz.

Generic Sensor Model
For proposals and early design phases the sensor is best modeled with a simple linear approach. In later design phases where the nonlinear aspects of the sensor response cna be modeled. This is frequently unnecessary unless the limits of your sensors and controllers are being pushed.
The simple model starts with a transfer function that represents the frequency response of the sensor. In addition to the frequency response of the sensor noise is modeled (simple band-limited white noise or PSD derived time history noise). Sensors are usually designed (and electronics or software added) to provide a linear response.
Sensor Noise
Most vendors provide noise measured on the sensor's output. (Be careful some vendors provide noise on the sensor input.) Noise will limit system performance. Noise passes straight through your control system to your output.
Nonlinear Models
Nonlinear models of sensors typically include Quantization effects and hard nonlinearities from software. Software thresholds can cause abrupt step changes to the output or to a control signal; these are what I am calling hard nonlinearities. Obviously these hard nonlinear steps can cause abrupt transient errors in the system. The abrupt steps will cause transients which need to settle before the system perofrmance will return to the expected behavior.
Nonlinear models are typically much more difficult to model. Validation is even more difficult and time consuming. Save these for later development stages where lots of test data can be taken and you have weeks or months to really dive into the data.
Possibly Stale Data Disclaimer
Please be careful how you use this data. It may be useful in an educational sense but system design decisions should be made using the manufactuerer's website only. This data was collected in Sept. and Oct. of 2008. As time progresses this data may become obsolete.
Data Quality Disclaimer
I've collected this data from various websites including sites that are not the manufactuerer's. Use the data for reference only and double check the performance parameters before making any vital decisions.
