  • Control loop performance monitoring in variable frequency drive
    Patent number: 11888420
    Abstract: Disclosed is a method for control loop performance monitoring in a variable frequency drive. A set of data is inputted to one or more control loop performance monitoring algorithms comprised in the variable frequency drive, wherein the set of data comprises at least a measured value of a process variable, a target value for the process variable, a set of controller input parameters, and a controller output. An output from each of the one or more control loop performance monitoring algorithms is obtained based at least partly on the set of data. One or more key performance indicator values indicative of control loop performance are determined based at least partly on the output from each of the one or more control loop performance monitoring algorithms. The set of controller input parameters is adjusted based at least partly on the one or more key performance indicator values.
