Design of a soft sensing technique for measuring pitch and yaw angular positions for a Twin Rotor MIMO System.

: This paper presents a soft sensor design technique for the estimation of pitch and yaw angular positions of a Twin Rotor MIMO System (TRMS). The objective of the proposed work was to calculate the value of pitch and yaw angular positions using a stochastic estimation technique.  : Measurements from optical sensors were used to measure fan blade rotations per minute (RPM).
