CSTR plays a vital role in almost all the chemical industries. Continuous Stirred Tank Reactor (CSTR) is a highly nonlinear process. The CSTR process is analysed for stability conditions by investigating the eigen values. Also Phase plane trajectory is constructed to analyse the CSTR. CSTR exhibits stable and unstable steady state at different regions. Control of CSTR in the complete range is a...

Continues Stirred Tank Reactor (CSTR) is an important issue in chemical process and a wide range of research in the area of chemical engineering. Temperature Control of CSTR has been an issue in the chemical control engineering since it has highly non-linear complex equations. This study presents problem of temperature control of CSTR with the adaptive Controller. The Simulation is done in MATL...

Continuous Stirred Tank Reactor (CSTR) here is considered as a nonlinear process. The CSTR is widely used in many chemical plants. Due to changes in process parameters the accuracy of final product can be reduced. In order to get accurate final product the faults developed in CSTR during the chemical reaction need to be diagnosed. If not, the faults may lead to degrade the performance of the sy...

Many types of controllers were applied on the continuous stirred tank reactor (CSTR) unit to control the temperature. In this research paper, Proportional-Integral-Derivative (PID) controller are compared with Fuzzy Logic controller for temperature control of CSTR. The control system for temperature non-isothermal of a CSTR will produce a stable response curve to its set point temperature. A ma...

Continuous stirred-tank reactors (CSTR) are widely applied in the chemical, food, and pharmaceutical engineering fields. The micro-scale fluid dynamics are important for the optimal processing study since they have a dominating influence on the overall performance of the reactor. In this article, 3-dimensional Computational Fluid Dynamics (CFD) simulations are carried out to portray the flow ch...

Anaerobic digestion is an environmental key technology in the future bio-based economy. To achieve functional stability, a minimal microbial community diversity is required. This microbial community should also have a certain 'elasticity', i.e. the ability to rapidly adapt to suboptimal conditions or stress. In this study it was evaluated whether a higher degree of functional stability could be...

This paper present three different control strategies based on PI Control, PID control and Two degree of freedom PID control for Continuous Stirred Tank Reactor (CSTR).CSTR which offers a diverse range of application in the field of chemical engineering as well as in the control engineering and is an attractive research area for process control researchers. Our objective is to control the tempe...

The non-isothermal continuous stirred tank reactor (CSTR) is a classical yet complex case study of nonlinear dynamical systems. Power-shaping control is a recent approach for the control of nonlinear systems based on the physics of the dynamical system. In this paper we apply the power-shaping control approach to the nonisothermal CSTR study case. A global Lyapunov function is derived for the o...

The paper presents a method for H-infinity controller design for a system affected by parametric uncertainty. The proposed method is based on minimising infinity norm of sensitivity function of the nominal system. The design approach is verified by robust stabilization and control of an unstable and perturbed continuous stirred tank reactor (CSTR) with hydrolysis of Propylene Glycol. The contro...

Abstract-The asymptotic stability regions for the patterned steady-state solution in a two-particle catalytic CSTR, established by Arce and Ramkrishna (1991, A.IC1I.E. J. 37,98-l lo), are constructed using two approaches, Liapunov’s direct method and the construction of a trapping region. In addition, the trapping regions are also constructed for uniform steady-state solutions. Stability region...
