| Abstract: | The operating condition of closed-chamber is widely used in industry and national defence. And it will be spaciously developed in the future. So it is very important to get the in-wall temperature of closed-chamber during millisecond range heat transfer. Based on the analyses of principle and structure, the in-wall temperature measurement is studied using the soft-sensing method. The soft-sensing model and corresponding solution are given. With a case, it is concluded that the in-wall temperature during millisecond range heat transfer in closed-chamber can be measured, adopting soft-sensing method, selecting the slowly changing temperature as the secondary variable and using the given model and solution. |
