A Design Study for Thermal Control of a CVD Reactor for YBCO
نویسندگان
چکیده
Active thermal control of a reactor for YBa2Cu3O7-x chemical vapor deposition is studied using a nonlinear heat transfer model validated by preliminary component testing. LQR and LQE methods are applied to the linearized model for observer-based control. Convergence rates of the controller and observer are indicated by closed-loop eigenvalues and disturbance rejection is assessed with H2 and H∞ norms. Design tradeoffs are quantified with these measures by varying model parameters. Maximum errors in control and estimation for a nominal design case are both 21 K, and longest timescales are 45 seconds and 10 seconds for the controller and observer, respectively.

Thermal-Hydraulics analysis of pressurized water reactor core by using single heated channel model
Thermal hydraulics of nuclear reactor as a basis of reactor safety has a very important role in reactor design and control. The thermal-hydraulic analysis provides input data to the reactor-physics analysis, whereas the latter gives information about the distribution of heat sources, which is needed to perform the thermal-hydraulic analysis. In this study single heated channel model as a very f...

متن کاملA Comparison of Different Control Design Methods for the Linearized CSTR Temperature Model
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...
