Self-repairing nonlinear control and its application to chemical reactor
نویسنده
چکیده
Against sensor failures, this paper presents a new design method for a self-repairing nonlinear control system (SRNCS). The proposed system can automatically replace the failed sensor with healthy backup if the sensor failure is found. The nonlinear detection filter guarantees exact and early fault detection, and the failure can be detected within a finite time prescribed by a design parameter of the filter. Also, in this paper, the proposed SRNCS is applied to a wellknown continuous stirred-tank reactor, and the effectiveness is confirmed through several numerical simulations.

متن کاملApplication of a self-learning controller with continuous control signals based on the DOE-approach
The paper introduces the concept of dynamic output elements (DOE), a novel approach to generate continuous control signals within a self-learning neural control architecture. Using DOEs the control signal is not determined by the decision of the control unit directly, but rather dependent on the temporal sequence of these decisions. Thus the basic mechanisms of decision making and learning are ...
متن کاملChaos Control in a Non-Isothermal Autocatalytic Chemical Reactor
In this paper, a reaction system consisting of two parallel, non-isothermal autocatalytic reactions in a Continuous Stirred Tank Reactor (CSTR) has been considered. Reactor chaotic behavior is possible for certain values of system parameters. Two types of controllers are designed and compared in order to control both the reactor temperature and the product concentration. T...

Tubular chemical reactor are units frequently used in chemical and biochemical industry. From the system theory point of view, tubular chemical reactors belong to a class of nonlinear distributed parameter systems. Their mathematical models are described by sets of nonlinear partial differential equations (PDR). The methods of modelling and simulation of such processes are described eg. in (Luy...
متن کاملHybrid Predictive Control of Nonlinear Process
Abstract: In this paper hybrid fuzzy model based predictive control (HFMBPC) is addressed, proposed and tested. The proposed hybrid fuzzy convolution model consists of a steady-state fuzzy model and a gain independent impulse response model. The proposed model is tested in model based predictive control of the concentration control in the chemical reactor, manipulating its flow rate. The paper ...
