Control unit with gain changing means responsive to operating conditions.

摘要

A basic gain providing unit (45) provides a basic gain K0. A boundary detecting unit (42) divides a nonlinear characteristic of a nonlinear component into a plurality of partial characteristics with a boundary interposed between two adjacent ones of the partial characteristics and detects each boundary. A gain changing unit (46) changes the basic gain in response to an output of the boundary detecting unit (42). <IMAGE>
