CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To realize a control device capable of maintaining high control performance for a plant with input and output characteristics changing each moment and reproducing a control input advantageous in a specific state with the deviation of a part of a control output being apparently 0. SOLUTION: The control device 5 includes a sliding mode controller 51 for repetitively calculating linear input and non-linear input with reference to individual state variables for each control output including the time integral of the deviation of a first control output and a target value x1zand others x1y, the time integral of the deviation of a second control output and a target value x2zand others x2y, and a correction control part 52 for making polynomial S2zx2z+S2yx2yto be 0 for the state variables x2zand x2yfor the second control output defining the non-linear input in a specific period with the deviation of the second control output regarded as 0.
