“…In general, the capacity of ventilation control system based on sprinkle process decreases the energy usage and improves environmental condition. Hung et al [8] studied an interesting controlling method by advance setting of the intelligent predetermined control method (IPCM) in order to improve the use of energy and water. An increase in temperature with a stable RH under the condition of no load is considered to test the possibility of IPMC.…”

In order to provide the comfortable areas for human, the comfortable rooms are the basic needs area, controlled temperature, and relative humidity (RH). The aim of this study is to control and maintain the temperature and RH of the comfortable room using a proportional integral derivative (PID) controller tuned by metaheuristic optimization. In tuning gains of the PID controller, the modern metaheuristic optimizations, ant colony optimization (ACO), and symbiotic organism search (SOS) are applied and the performance of the proposed control system is compared to that of the traditional methods. In the experimental testing, the controlled room size is tested in the area of width 7.80 m, length 8.00 m, and height 3.80 m. The simulation results show that the performance of the proposed control system-tuned gains of PID controllers by using SOS algorithm has the least steady-state error with 15% rise time and also the overshoot can reach the setpoint. In the case of disturbance occurring in the system, the proposed control system is able to approach the setpoint. Therefore, the PID controller tuned by SOS algorithm can regulate the temperature and humidity of the comfortable room, proficiently.

“…The airflow from the axial fan can move along the chamber walls, significantly reducing instances of dead corners, producing unobstructed circulation, and improving the uniformity of the temperature and relative humidity. Furthermore, to simultaneously solve the problem of interference from the actuators in the same airflow loop, the concept of the independent flow loops is used from the previous study (Hung et al, 2015). In addition, to prevent affecting the airflow from the actuator into the test chamber, the inlet and outlet pipes must be tailored as tangential to the airflow shown in Fig.…”

“…In addition, with miniaturized heating and humidifying elements, it is not easy to realize heating and humidifying functions with reasonable range and speed, compared to their macroscopic counterparts. Although control algorithms can be utilized to optimize the heating and humidifying process, most of the reported algorithms are developed for standard "big" environmental chambers [12][13][14]. Their applicability on miniaturized systems still need to be investigated.…”

A miniaturized reliability test system for microdevices with controlled environmental parameters is presented. The system is capable of measuring key electrical parameters of the microdevices while controlling the environmental conditions around the microdevices. The test system is compact and thus can be integrated with standard test equipment for microdevices. By using a feed-forward decoupling algorithm, the presented test system is capable of generating a temperature range of 0–120 °C and a humidity range of 20–90% RH (0–55 °C), within a small footprint and weight. The accuracy for temperature and humidity control is ±0.1 °C and ±1% RH (30 °C), respectively. The functionality of the proposed test system is verified by integrating it with a piezo shaker to test the environmental reliability of an electromagnetic vibration energy harvester. The proposed system can be used as a proof-of-technology platform for characterizing the performance of microdevices with controlled environmental parameters.
