Abstract
A control device having control logics that respectively generate operated quantities by simutaneously parallel-processing observed quantities obtained from a controlled object. A switch selectively outputs one of the operated quantities to the controlled object based on instruction data.
Claims5
A control device, comprising:
- a first control logic that receives observed quantities from a controlled object and generates a first operated quantity by performing a real-time processing of the observed quantities based on a first program;
- a second control logic that receives observed quantities from said controlled object and generates a second operated quantity by performing a real-time processing of the observed quantities based on a second program;
- a switch means for selectively outputting one of the first operated quantity and the second operated quantity to the controlled object based on instruction data;
- a first computer that performs multi-task processing and includes the first control logic, the second control logic, and the switch means;
- and
- a second computer for modifying the first program when the switch means outputs the second operated quantity to the controlled object.
