Researchers developed a mathematical model to detect unbalanced loads in washing machines and tested its accuracy in a simulation.
The study created a mathematical model of a horizontal washing machine to understand how unbalanced loads affect different-sized loads. The model was divided into two parts: a regressor vector and an estimator vector. The researchers then compared their estimates of unbalanced loads, their location, and the machine's rotational moment of inertia to reference values in a simulation environment.
Abstract
In this study, an analytical concept is explored in the simulation environment, and an unbalanced load detection technique is examined to determine its applicability. To continue the development process, a mathematical model for a horizontal washer is developed to comprehend the characteristics of an unbalanced load with respect to various sizes of balanced loads. The mathematical model is then divided into a regressor vector and an estimator vector. Finally, estimates of the unbalanced load, the unbalance location, and the rotational moment of inertia are compared to their references in the simulation environment.
