ABSTRACT:
An electric controller system includes a comparator at the input of a processor, the processor including a program memory, an operation control unit and a data memory. A digital/analog converter is provided at the processor output. Analog/digital conversion is by means of a loop including the processor, digital/analog converter and comparator. The digital/analog output is also received by an analog signal hold means, the output of which is fed back to the comparator. A manual control circuit operable only in a manual control mode provides an alternative input to the analog signal hold means. Computations in the processor are thus based on a manual input through the hold circuit and comparator only during the manual control mode. Bumpless switching from the manual mode to an automatic mode is provided while further providing for a manual output with failure of the processor. Further embodiments include a multiplexer at the input, a plurality of hold circuits and parameter setting circuits at the input.
