A novel measurement method of temperature model for bioreactor

Abstract

A novel measurement method of temperature model for bioreactor has been proposed. Temperature is the key parameter in monitoring the bioreactor operation. However, the system input signal of bioreactor is delayed, and model parameters are uncertain, so the output of temperature is non-steady-state. Many dynamic measurements are not steady so that it cannot be described by variables constant in time. In this paper, we adopt the monopulse signal as input so that the output of the bioreactor system is steady. This method has a powerful ability to steady the output of the bioreactor. In view of the measurement results, it can be seen that the model dynamic measurement approaches the real process. The analytical expression of the monopulse response for the temperature model of the bioreactor is obtained. The novel measurement approach is simple and can be easily adopted by industry.
