Abstract
An improved integrator for use in physical analog-computing systems is disclosed, featuring real-time dynamic amplitude scaling schemas that make use of an injected correction factor responsive to a contemporaneous change in an input dynamic-amplitude-scaling compensation factor. The injected correction factor is designed to reduce or eliminate transient output perturbations due to the amplitude scaling change. The disclosures discussed have real-world applications for physical analog computers and hybrid computers used to control and manage many types of industrial-control systems.
Claims16
A method for operating a physical analog computer adapted to receive and process at least one input signal, the physical analog computer defining an integrator downstream of said at least one input signal and further defining an output downstream of said integrator, the method comprising the steps of:
- applying a first change to a scaling value at the at least one input signal;
- at the integrator, injecting a first one-time compensation factor to the integrator, the timing and magnitude of the first one-time compensation factor selected to reduce any perturbation that would be observed at the output in the absence of the injection of the first one-time compensation factor.
A physical analog computer adapted to receive and process at least one input signal, the physical analog computer defining an integrator downstream of said at least one input signal and further defining an output downstream of said integrator, the analog computer further comprising:
- first means responsive to increases and decreases in a magnitude of the at least one input signal for applying a first change to a scaling value at the at least one input signal;
- second means, responsive to any change to the scaling value, for selecting a timing and magnitude of a one-time compensation factor for injection at the integrator, the timing and magnitude of the first one-time compensation factor selected to reduce any perturbation that would be observed at the output in the absence of the injection of the first one-time compensation factor.
