By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News – New research on Machine Learning is the subject of a report. According to news reporting originating from Houghton, Michigan, by NewsRx correspondents, research stated, “This paper presents the application of machine learning classification algorithms to identify and classify different heat release rate (HRR) shapes to control the combustion for an optimal multi -mode low -temperature combustion (LTC) engine operation. Low -temperature combustion engine produces low nitrogen oxides (NOx) and soot emissions and offers high thermal efficiency.” Funders for this research include National Science Foundation (NSF), U.S. Department of state, Bureau of Educational and Cultural Affairs, Fulbright Program.Our news editors obtained a quote from the research from Michigan Technological University, “But high in -cylinder pressure rise rates limit the operating range of the LTC engine. Therefore, it is imperative to control combustion in the LTC engine for safe operation. To this end, the HRR traces for over six hun- dred engine operating conditions are classified using supervised (i.e., Decision Tree, K -Nearest Neighbors (KNN), and Support Vector Machines (SVM)) and unsupervised (i.e., Kmeans clustering) machine learning approaches to segregate different combustion regimes based on HRR shape. Kmeans clustering was not successful in classifying the HRR shapes. Among different supervised machine learning techniques, SVM has proved to be the best method, having an overall classifier prediction accuracy of 92.4% for identifying the distinct shapes using normalized HRR data. In addition, three classifiers have been trained based on the combustion parameters and control inputs. These classifiers are then used as scheduling variables to develop predictive models. A model predictive control (MPC) framework is developed to control multi -mode LTC engine on cycle -to -cycle basis.”
