Predictive stochastic feedforward-feedback control of a heat exchanger-stirred tank system

An optimal stochastic feedforward-feedback control scheme is implemented on a heat exchanger-stirred tank system using an on-line minicomputer. Because variations in the measured disturbance variable affect the process output (controlled variable) before the compensating action can become effective, the feedforward action must be predictive in nature. Statistical time series models are used to model both the measured and unmeasured disturbances …
