A robust form of self-tuning controller than has been designed to replace conventional PID controllers in a number of HVAC applications is described. The controller is based on a version of the generalized predictive control algorithm that uses default values for most of its parameters and requires selection of only one commissioning parameter: the control sampling interval. Special jacketing software has been developed to implement a set of expert rules, which are not application dependent, but which supervise the operation of the on-line parameter estimator and the calculation of control action. This ensures satisfactory operation of the controller in most situations. The performance of the controller is evaluated under demanding conditions using a detailed computer simulation of the central air handler in a building.
