Abstract
A controller includes a memory device and an execution device that executes first and second operation processes, a switching process, and a recording process. The first operation process operates an operated unit by an operated amount, which is calculated on the basis of a state variable, using an adapted data set. The second operation process operates the operated unit by an operated amount that is defined by a relationship defining data set and the state variable. The switching process switches a process that operates the operated unit between the first operation process and the second operation process. The recording process obtains a value of the state variable used in calculation of the operated amount using the first operation process during an operation of the operated unit using the second operation process. The recording process also records time-series data of the obtained value of the state variable in the memory device.
