Systems and methods for mitigation of oscillation in a closed-loop system
In accordance with embodiments of the present disclosure, a system may include a feedback controller and logic. The feedback controller may be configured to, based on a setpoint value and a measured process value calculate an error between the setpoint value and the measured process value and generate a driving signal based on the error. The logic may be configured to determine if oscillation is present in the driving signal, determine if oscillation is present in an operational parameter other than the driving signal such that oscillation of such operational parameter may cause oscillation in the measured process value, determine if oscillation present in the driving signal is correlated with oscillation present in the operational parameter, and adjust a control parameter of the feedback controller responsive to determining that oscillation present in the driving signal is not correlated to oscillation present in the operational parameter.
