Problems solved by technology

Multivariable control systems are now generally regarded as a class of advanced complex systems: advanced because multivariable control systems can provide centralized control for industrial processes involving multiple variables; complex because multivariable systems are more complex than single-variable systems The control is more difficult, the equipment requirements are more complicated, and the control structure of the system is also more complicated
In addition, from the perspective of control theory, advanced and complex control systems can achieve higher control standards, so the theoretical difficulty exceeds the usual simple single-variable process control

Abstract

The invention relates to a control method of a multivariable unstable system based on a combined integral controller. The method comprises the following steps of: employing a dynamic decoupling controller to decouple the multivariable unstable system into a plurality of independent subsystems, and designing a combined integral controller for the independent subsystems. The control structure is simple, the parameter setting is intuitive and convenient, and the system still has a good control performance, a high anti-jamming capability and a good robust stability in conditions of interference and model mismatching.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a control method for a multivariable unstable system based on a combined integral controller. Background technique [0002] In many actual process industrial processes, there are specific requirements as follows: (1) The system is safe and stable during operation; (2) The system has good adjustment performance; (3) The system has certain anti-interference ability. However, when encountering a multivariable system (MIMO), some specific situations may arise due to its complex internal structure. [0003] In a MIMO system, due to a certain degree of coupling among multiple variables, if one of the input signals changes, multiple outputs associated with it will also change accordingly. If the input and output are matched, one input and output can be used to form a closed loop to effectively control it, but the mutual influence cannot be completely eliminated, so this metho...
