The paper focuses on the application of neural network techniques in fault detection and diagnosis. The objective of this paper is to detect and diagnose the faults to a continuous stirred tank reactor (CSTR). Fault detection is performed by using the error signals, where when error signal is zero or nearly zero, the system is in normal condition, and when the fault occurs, error signals should...

A new modular photochemical continuous stirred-tank reactor (CSTR) design is described, based upon the development of light-source units that can be fitted to previously described fReactor CSTR platform. In addition use in homogeneous reactions (e.g., photoredox-catalyzed hydroamination), these are especially well suited handling multiphasic mixtures, exemplified here solid–liquid (Wohl–Ziegler...

continuous stirred tank reactor (cstr) has particular importance in chemical industry. cstr has usually a nonlinear behavior which makes it difficult to control. the reactor has two parameters: the concentration and temperature of mixture both of which are uncertain. this case of cstr has large disturbance in domain. in order for disturbance rejection, a controller has to be designed. in this p...

This paper presents the design and performance analysis of Differential Evolution (DE) algorithm based Proportional-Integral-Derivative (PID) controller for temperature control Continuous Stirred Tank Reactor (CSTR) plant in chemical industries. The proposed work deals about order to improve CSTR. In this, process is controlled by controlling liquid through manipulation coolant flow rate with h...

The simultaneous dynamic equations for substrate and biomass mass were used to assess the UASB reactor performance of municipal wastewater. The dynamic model equations were solved by using a m.file in MATLAB2011a command window and dynamic equations for substrate and biomass. The objectives of this paper are (1) To develop a simple CSTR model for simulation of UASB reactors performance assuming...

The paper deals with adaptive control of a continuous stirred tank reactor (CSTR). A nonlinear model of the process is approximated by a continuous-time external linear model. The parameters of the CT external linear model of the process are estimated using a corresponding delta model. The control system with two feedback controllers is considered. The controller design is based on the polynomi...

In this paper, the design of a robust static output feedback controller is presented. This problem is transformed to solving of linear matrix inequality (LMI) problems. A computationally simple LMI based non-iterative algorithm is used. The design procedure guarantees with sufficient conditions the robust quadratic stability and guaranteed cost. The presented approach is applied for robust cont...

This chapter describes the design of controllers for the ideal CSTR using soft computing techniques namely, genetic algorithm and fuzzy logic. In this chapter, an attempt has been made to obtain the optimal PI controller parameters for each operating region using GA technique. GA based PI implements the characteristics of global optimization to optimize the PI control parameters Kp and Ki to pr...
