The present invention provides a roller mill control method capable of automatically controlling a roller mill which is comparatively difficult to operate for operation in an optimum operating condition, and a roller mill controller for carrying out the roller mill control method. The roller mill controller stores beforehand a roller mill characteristic model representing the relation between changes in the values of the operating condition variables detected by a detecting unit (2) and operating parameters, restrictions on the values of the operating condition variables and the operating parameters, an index of performance for evaluating the values of the operating condition variables and the operating parameters. A Simplex algorithm calculation system (5) included in an optimizing control arithmetic unit (3) calculates changes in the operating parameters by a Simplex algorithm by using the roller mill characteristic model, the restrictions and the index of performance to select the values of the operating condition variables detected by the detecting unit (2) so that the index of performance is optimized under conditions meeting the restrictions, and then, a main control unit (4) controls the roller mill on the basis of new operating parameters.
A roller mill control method which controls an operating condition of a roller mill during operation thereof by adjusting values of operating parameters of the roller mill on the basis of values of operating condition variables representing the operating condition of the roller mill, said roller mill control method comprising the steps of:
