We would like to rise water temperature with a heater. Oulet temperature must be equal to the set point temperature (80dlT-C). Proportional (P), Proportional-Integral (PI) and Proportional-Integral-Derivative (PID) control are used and the respective results are compared. Inlet water temperature... Platforms: Matlab

We would like to rise water temperature with a heater. Oulet temperature must be equal to the set point temperature (80dlT-C). Proportional-Integral-Derivative (PID) control is used. Inlet water temperature is equal to 20dlT-C. Water flow is equal to 10 m3/hr. Tank volume is equal to 100 m3.... Platforms: Matlab

MATLAB is one of the best pedagogical software tools to illustrate and visualize concepts in engineering programs.
