Themerit and performance for disturbance estimation of a hardware based embedded system that implements an observer is evaluated. An existing rotational mechanics system that is initially decoupled from the observer is presented as a load where known physical manifestations of disturbance is modelled by piecewise linear approximations. A coupling is established by connecting together a microcontroller platform with real time implementation in embedded code functions to a specially constructed electro-mechanical system that is driven by a Brushed DC (BDC) motor. A select number and type of synthesized disturbance is use to drive a magnetic particle brake for a response then torque measurements are obtained, while the observer forms in a hardware in the loop function. The open loop physical model simulation, bench measurements and the output of the observer are found to be in good agreement at experimental level. A diagnostic tool for disturbance detection and estimation of a design is found to be technically plausible.
