Abstract
A method for controlling a controlled process in response to an input signal and a disturbance signal includes modeling the controlled process in a process model; controlling the process model by a first controller; isolating the first controller from the disturbance signal so that the first controller may be designed for an optimal response to the input signal; driving the first controller by a first drive signal proportional to the difference between the input signal and a process model output signal; isolating a second controller from the input signal so that the second controller may be designed for an optimal response to the disturbance signal; and driving the second controller by a second drive signal proportional to difference between a process output signal and the process model output signal.
Claims7
A method for controlling a controlled process in response to an input signal and a disturbance signal, the method comprising:
- predicting a process output to create a predicted process output signal;
- generating an error signal based on the input signal and the predicted process output signal;
- generating a first control signal based on a disturbance signal and the error signal;
- and
- processing the error signal and the first control signal to generate a process control signal to control the controlled process;
- wherein the error signal is generated independently of the first control signal and process control signal.
A method for controlling a controlled process in response to an input signal and a disturbance signal, the method comprising:
- modeling a controlled process and generating a process model signal in a first partitioned feedback loop;
- generating a predicted error signal proportional to the difference between the input signal and the process model signal;
- generating a first control signal proportional to the difference between the predicted error signal and an output signal proportional to the output of the controlled process and the disturbance signal in a second partitioned feedback loop;
- processing the predicted error signal and the first control signal to generate a process control signal to control the controlled process;
- wherein the first partitioned feedback loop operates independently of the second partitioned feedback loop.
