Abstract

The invention relates to a multi-model adaptive control method and a system of a continuous stirred tank reactor, the temperature of the continuous stirred tank reactor is controlled, the application range is expanded, an incremental model description of a continuous stirred tank reactor temperature control system is proposed, a new parameter estimation method is proposed, and the multi-model adaptive control method does not need to assume global boundness of a non-linear term of the system. The problem of non-minimum phase of the continuous stirred tank reactor can be solved via the introduction of a pole placement controller. The invention brings forward a new non-linear control structure capable of improving the precision of the multi-model adaptive control method. Compared with the conventional non-linear multi-model adaptive control method, the multi-model adaptive control method is promoted to the non-minimum phase continuous stirred tank reactor temperature control system, and the adaptability of a multi-model adaptive controller can be effectively improved.

Description

technical field [0001] The invention relates to a control method and system, in particular to a multi-model self-adaptive control method and system for a continuous stirring reactor. Background technique [0002] With the continuous development of my country's industrialization process, the industrial system is gradually changing from a simple control system composed of less equipment to a large complex system characterized by multi-stage and multi-equipment. Such large-scale nonlinear systems often have strong nonlinearity, multiple equilibrium points, large parameter variation ranges, and parameter jumps, etc., which cannot be simply described by a single linear model. Therefore, the classical control theory for linear system design cannot obtain satisfactory control effects. [0003] The continuous stirring reactor is an indispensable production tool in the chemical, pharmaceutical and other industrial production processes, and its operating conditions directly affect th...
