| Abstract: | Recently, applications of the control of ground temperature have been widely used for the maintenance of lawns and underground storage tanks, road surface temperature control, etc. This paper presents a predictive bang-bang control to perform a real-time and practical control method. A time series of the future exterior boundary condition, used for the predictive control, is predicted by the Kalman filter technique. The basic equation of the ground temperature is discretized by the finite element method in space and the Crank–Nicolson method in time. To obtain the predictive control temperature, the performance function is minimized at every time step by the Sakawa–Shindo method. © 1997 John Wiley & Sons, Ltd. |
