Abstract

The invention relates to a semi-physical simulation system of an AC-DC-AC metallurgy rolling mill transmission system. The semi-physical simulation system comprises: a physical control unit, which includes a rolling mill transmission system controller outputting a control signal; a real-time simulation unit, which includes a real-time simulator, is provided with an operated main circuit module of the rolling mill transmission system and is used for receiving and transmitting an electric signal by a corresponding signal interface to carry out analog simulation calculation; and a signal conversion unit, which is connected between the physical control unit and the real-time simulation unit and is used for converting the control signal outputted by the physical control unit into an electrical signal that can be received by the real-time simulation unit and providing the electrical signal to the real-time simulation unit, converting an analog simulation result outputted by the real-time simulation unit into an actual work signal and providing the signal to the physical control unit, thereby realizing simulation testing on the rolling mill transmission system controller.

Description

technical field [0001] The invention relates to a simulation control technology, in particular to a semi-physical simulation system of an AC / DC metallurgical rolling mill transmission system. Background technique [0002] The transmission conditions of metallurgical rolling mills have the characteristics of severe load mutation, high overload multiples, and very high requirements for response speed and reliability. In order to ensure the safe and reliable operation of the transmission system, the development of the metallurgical rolling mill controller must be based on strict test foundation. In this regard, the following two methods are usually used in the prior art to debug and verify the metallurgical rolling mill controller: [0003] 1. Debugging and verification on the real rolling production line; [0004] 2. Use the engineering object motor to force method to determine whether the control model and response ability meet the requirements. [0005] The method of rese...
