Prof. Dasgupta received his Bachelor and Master of Science Degree in Electrical Engineering with Power and Control Systems as a major from Indian Institute of Science and Technology (IIEST) in India.
After coming to United States from India after graduation, Prof. Dasgupta earned Master of Science Degree in Engineering Management with Operations Research as a major from Northeastern University. After that he received Post Master’s Degree (EE Degree) in Electrical Engineering with Control System as a major from Northeastern University. At Northeastern Prof. Dasgupta completed all the coursework for PhD degree. Prof. Dasgupta is a Registered Professional engineer in the State of Massachusetts.
Prof. Dasgupta worked for Ever Source company (previously known as Boston Edison Company) for more than twenty five years where he worked in various departments like transmission, distribution and relaying groups. He mainly worked for a 700 megawatt nuclear generating station within Eversource. At Eversource, he also held the role of Division Manager for Power and Controls Division for 15 years. He has over 15 years of oversight and supervision experience.
Before coming to Wentworth Institute of Technology, Prof. Dasgupta worked as an Adjunct Professor (part time) at Northeastern University for more than 11 year in the Graduate School of Engineering. He mainly taught the courses in Operations Research at Northeastern University. He also, taught at Suffolk University as an adjunct Professor.
Prof. Dasgupta worked for Wentworth University for more than 19 years in the Electrical and Computer Engineering Department. He taught various courses at Wentworth which includes. Motors and Controls, Power Systems, Analog and Digital Control Systems, Analog and Digital Communications, Digital Signal Processing, Electromechanical Systems etc. Major achievements during Prof. Dasgupta ‘s tenure at Wentworth are as follows: developments of Motors and controls lab, introduction of Power Systems course as an elective, development of Feedback and Controls lab, development of Digital signal processing lab, development of Analog and Digital Communication lab and introduction of PIC microcontroller for Microcontroller course. Prof. Dasgupta was a member of BELM committee where he contributed to the development of Master of Science Degree Program. Prof. Dasgupta served as a “Grant Reviewer” for National Science Foundation (NSF).
Internationally, Prof. Dasgupta spent one semester as a sabbatical in India where he developed Digital Signal Processing curriculum in addition to teaching graduate courses. He also spent one semester in 2018 as a visiting Professor at American University in Vietnam (AUV) in Danang, Vietnam.
Prof. Dasgupta was a past District Vice President of International Society of Automation (ISA), Director of Controls and Robotics Division in ISA and Member of IEEE. He gave numerous seminars in various organization like ISA, IEEE and ASEE etc. including various Universities in USA and outside USA. He also, published papers in the power and controls areas.
After retirement from Wentworth University, Prof. Dasgupta spent one semester starting January thru May 2019 at American University in Vietnam (AUV) as a Dean of Engineering and Computer Science in addition to his teaching assignment at AUV. Presently, Prof. Dasgupta is teaching at Northeastern University as an adjunct Professor.

Abstract

Electromechanical system course offered at XXX focuses on modeling mechanical & electrical dynamic systems. It is a 4 credit course with a 3 hour lecture and a 2 hour lab each week. The objective of this course is to model and analyze the dynamic behavior of electromechanical system. Software application programs are used to facilitate how electromechanical systems are analyzed, simulated and designed. In the past, the cantilever beam experiment was highly simulation based. Students used MATLAB and Simulink, SimScape Multibody to obtain the system performance. Most of the simulations represented ideal cases, students are lack of connection with the simulated system and the real system. In order to expose students to real dynamic systems, some physical lab experiments are needed.

This paper describes the experimental design of a cantilever beam system, which illustrates two different cases: free vibration and vibration due to rotating unbalance. Those concepts were taught in lecture and were reinforced with the experiments. For a series of two experiments, students analyzed the real beam system by characterizing the damping coefficient of the beam. They observed the frequency changes of the beam with various loads added. Students also observed resonant frequency of the beam due to unbalanced rotation. At the end, the experimental results were compared to the theoretical results. They provided positive feedback for the newly developed experiments. These labs helped them understand the course concepts better.
