| Summary: | This project describe the development of temperature regulation for herb drying
system. The most important factor for herb drying is temperature. The purposes of
temperature are to maintain the quality of herb, prevent degradation of product and
also to fast the dry process. The design of this project based on PID and MRAC. PID
used as the benchmark on this project. For PID controller, P and PI controllers also
build to do the comparison. There are two model of MRAC used which are standard
MRAC and modified MRAC. Model reference adaptive control without integral
(MRACWI) lastly achieve a better regulation temperature for herb drying system.
Based on the results, it is shows that the MRACWI have better percentage
improvement in term of settling time compared to PID and standard MRAC. For
percentage of performance for MRACWI with 45℃, in terms of settling time it has
80.58% better than PID. For 50℃, it has 71.75% while when 55℃, it has 64.85% and
56.35% when 60℃. In conclusion, the biggest temperature, the lesser percentage of
performance. It also shows that MRACWI has none overshoot. It provide that
MRACWI is capable to provide robust and precise performance in controlling the
temperature and produce better performance in terms of rise time, settling time and
percentage overshoot as compared with PID controller and standard MRAC. |
