“…After thermal treatment, wood is less hygroscopic than kiln-dried wood. [1][2][3][4] This can be noted as reduced swelling and shrinkage, which can be as much as 50% for higher temperatures (>200 C) and longer times. In that context, the sorption and desorption characteristics are also changed.…”

The aim of this study was to determine the changes in physical properties of Paulownia (Paulownia elongata) wood, a fast-growing species, during heat treatment at three different temperatures (160, 180, and 200 C) and durations (3, 5, and 7 h). After heat treatment, changes in swelling, density, color, and equilibrium moisture content at 35, 65, and 85% RH were investigated. The results indicated that the minimum and maximum decrease swelling ratios were 6-46% for tangential, 4-32% for radial, and 12-64% for longitudinal. The equilibrium moisture contents were 1-26% for 35% RH, 1-33% for 65% RH, and 1-38% for 85 RH, respectively; the density of air-dried and oven-dried samples decreased by 1-16% and 1.5-15%, respectively, and color changes values (L Ã ) were 10-40%.

“…Twist, checks, and collapse were measured to investigate the drying defects. The check was determined with a Mitutoyo digital gauge following the methods described by Korkut & Guller [ 11 ]. The little check considered for ≤1.0 mm in depth occurred in the dried sample while ≥1.0 mm in depth was in the group of severe checks for this study.…”

“…To overcome this deficiency, a large amount of improvements to reduce the chatter have been developed. In Korkut and Guller (2007), Sun et al (2011), Hsu and Chang (2016) and Tang et al (2013), intelligent, adaptive and fractional enhancements for the chattering reduction have been investigated. Likewise, the methods based on exponent approach law have been proposed in Wang et al (2016) and Hou and Zhang (2016).…”

This paper deals with the design of sliding mode controllers for the wood drying process. Prediction models based on a nonlinear autoregressive model with exogenous inputs of dry-bulb temperature and equilibrium moisture content during drying were built to design the controllers. A comparative study was performed in order to determine the controller presenting the better performance in practical application. The compared strategies were sliding mode control based on exponent approach law and variable rate approach law. The second controller was introduced to optimize the controller while reducing the chattering phenomenon in comparison with the exponent approach law. To demonstrate the effectiveness of the proposed control strategies, simulation and experimental results were presented.
