Instrumentation and Process Control in Food Industry

By Prof. Ashis Kumar Datta   |   IIT Kharagpur
Learners enrolled: 1688
The course aims to introduce the first principles of controlled systems as sensed by instruments and fedback for effective control strategies. Design of stable controllers based on proportional – integral – derivative combinations will be the final outcome of the course objectives. The participants are expected to apply transform calculus to obtain real time solutions to second order system response.

PRE-REQUISITE: Transform Calculus/ Complex Algebra.

Registration url: Announcements will be made when the registration form is open for registrations.
The online registration form has to be filled and the certification exam fee needs to be paid. More details will be made available when the exam registration form is published. If there are any changes, it will be mentioned then.
Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc.


Average assignment score = 25% of average of best 6 assignments out of the total 8 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

Certificate will have your name, photograph and the score in the final exam with the breakup.It will have the logos of NPTEL and IIT Kharagpur. It will be e-verifiable at nptel.ac.in/noc.

Only the e-certificate will be made available. Hard copies will not be dispatched.

Once again, thanks for your interest in our online courses and certification. Happy learning.
