1.3 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 are listed as vibrating so I assume this mean they are MEMs gyros with a vibrating proof mass. 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 piezo accelerometers are rated from 2 to 500 g with bandwidths ranging from 250 to 2400 Hz.

3 Generic Sensor Model

Basic Sensor Model

Most sensors can be modeled simply. The simple model starts with a transfer function that bounds 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).

Typically sensors are designed (and electronics or software added) to provide a linear response. Sometimes the sensor is designed to provide that linear response over the largest possible frequency range. Other vendors will add the electronics and software to reduce noise or improve phase response.

3.1 Sensor Noise

Generic Random Noise Model

Some vendors provide noise specifications from noise measured prior to the sensor. However, most provide noise measured on the sensor's output. This noise will limit your control system performance. Noise passes straight through your control system to your output.

3.2 Nonlinear Models

For proposals and early design phases the simple, linear, model is typically adequate. Nonlinear models of sensors typically include Quantization effects and hard nonlinearities from software. Hard nonlinearities such as software thresholds can cause abrupt step changes to the output or to a control signal. Obviously these hard nonlinear steps can cause problems for a controlled system.

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.
