PI Controller Setpoint Weighting for Overshoot-Response Trade-Off

The patent applies dynamics by making the setpoint weighting coefficient variable rather than constant. The coefficient dynamically adapts based on the error signal magnitude: when error is large, full weighting is applied to minimize overshoot; when error is small, weighting is reduced to improve response time. This dynamic adjustment resolves the contradiction between overshoot reduction and response time maintenance.

The patent changes the parameter of setpoint weighting coefficient from a fixed value to a variable that depends on the error signal. By modifying this parameter based on system state (error magnitude), the corrector achieves different behaviors at different stages: aggressive overshoot prevention when needed, and fast response when error is small, thus resolving the performance contradiction.

The patent applies self-service by enabling the corrector to automatically adjust its own setpoint weighting coefficient based on the error signal without requiring external iterative tuning. The system serves itself by using the error magnitude to directly determine the appropriate weighting coefficient, eliminating the need for complex adjustment procedures while maintaining flexibility.

The patent uses feedback by continuously monitoring the error signal and using it to determine the setpoint weighting coefficient. This feedback mechanism automatically adapts the corrector behavior to current system conditions, providing adjustment flexibility without requiring complex external tuning procedures, thus reducing adjustment complexity.

The patent applies segmentation by separating the functions of response time improvement and noise filtering into distinct components: the variable setpoint weighting coefficient handles response time optimization, while the PI structure with integral action handles noise filtering. This functional segmentation allows achieving fast response without adding a derivative component that would amplify noise.

The patent uses an intermediary approach by introducing a variable weighting coefficient as a mediator between the setpoint and the PI corrector. This intermediary element enables response time improvement through dynamic weighting adjustment without requiring a direct derivative connection that would amplify measurement noise, thus avoiding the harmful effect while achieving the desired speed improvement.
