Claim One:
1. A discrete time control apparatus for controlling a system in continuous time, comprising: sampling/detecting means for detecting a controlled system variable at each sampling interval; control means for selectively switching operation on the system at each sampling interval between a binary mode and a continuous mode, the control means being responsive to an external input; discrete-time adaptive switching control means for (i) estimating and updating model parameters at said each sampling interval based on a manipulated variable to be applied to an actuator effecting the binary mode wherein the controlled variable is detected by said sampling/detecting means in order to adapt a discrete-time model to said system, and for (ii) selecting a sequence of predicted controlled variables over predictable sampling intervals in response to application of a possible controlled-variable sequence over certain sampling intervals to said discrete-time model, thereby determining a controlled variable for said actuator; continuous manipulated-variable sampling control means for computing parameters based on the discrete-time model estimated by said discrete-time adaptive switching control means for effecting continuous control on said system; and switching means for selecting, one at a time, said discrete-time adaptive switching control means and said continuous manipulated-variable sampling control means based on a target preset value and the present controlled variable.
