Abstract
Systems and methods for controlling and monitoring equipment in control systems. Adaptive mapping of system output change to amounts of applied control effort. Methods are disclosed to define, initialize, and tune a particularly efficient, log-spaced mapping. Self-tuning update methods cause the control map to improve with use and provides excellent convergence to the actual nonlinear relationship between control input and device output. As the mapping converges to the actual relationship, system performance is optimized when used for purposes of control. Methods pertaining to the specific instance of adaptive impulse control are disclosed. As the mapping converges and tracks what may be a time-varying relationship due to equipment wear or changing operating conditions, drift from baseline conditions can be detected.
