An adaptive control algorithm is developed that increases the performance of the temperature control system of a water heating boiler. In the control system, parameters of PI controller and compensator of load disturbances are adjusted on-line using modified gain scheduling approach that refers to a state model of the controlled process and on-line measurements of process variables. The gain scheduling is based on transfer functions of the control channel "fuel supply rate-temperature of outlet water" and the disturbance channel "flow rate of outlet water-temperature of outlet water" that are derived from the state model and up-dated on-line with the current measurements of state, disturbance and control variables. Optimal settings of the controller and compensator parameters are recalculated at each state estimation point.
