Abstract: Bioprocess control is often limited to regulation of temperature at constant values favorable to the microbial growth. Bioreactor control has become an active area of research in recent years. The design and analysis of traditional control systems are based on their precise mathematical models, which are usually difficult to achieve owing to complexity, non-linearity, time varying and incomplete characteristics of the existing practical systems. To overcome this problem, one of the most effective ways is to use a suitable control using fuzzy logic approach. In this paper, the temperature of the bioreactor in fermentation process is controlled using PID controller and fuzzy logic controller and their performances are compared through simulation studies using MATLAB software.
