ABSTRACT:
A microprocessor-based turbine speed controller which incorporates a set of permanently programmable memory devices for characterizing the control of turbine speed in real time is disclosed. A speed monitoring interface circuit included in the speed controller is governed by the microprocessor in accordance with the processing of one program stored in one or more of the permanently programmable memory devices to generate speed measurement data words representative of actual turbine speed. In addition, a power-on initialization circuit initializes the microprocessor at the time of power turn-on to process another program stored in one or more of the permanently programmable memory devices for initializing a plurality of predetermined registers contained in the speed controller corresponding to the characterized speed control operation to be performed by each. Further apparatus and programmed instructions for the control thereof are employed to detect a malfunction in program execution by the microprocessor. Additional apparatus is included to provide a speed control signal output and to condition a plurality of digital input and output signals. All microprocessor processing operations are synchronously time sequenced using the signals generated by a system clock.
