  • Proportional with variable bias batch reactor temperature control system
    Patent number: 5697436
    Abstract: An improved method of controlling the temperature of a batch reactor employing a cascaded master and slave controller architecture wherein the temperature of the reactor serves as the measured variable, MV.sub.1, in the master loop and the jacket temperature serves as the measured variable, MV.sub.2, in the slave loop and the feedback for the master loop, FB.sub.1, is intentional set equal to this measured variable, MV.sub.1, or to the master controller set point, SP.sub.1, corresponding to the temperature of the reactor thus inherently creating a bias feedback and proportional variable reset (PVR). The novel PVR temperature control system is useful in alleviating product variability caused by temperature control variation during heat, cod and hold steps.
