The Control Engineering class for the fifth-year students of Electronic Control Engineering Department, Sendai National College of Technology, is conducted in the form of lecture and experiment, and the PID controlled experiment has been carried out in the class since 1989. Moreover, the control theory is taught to the fourth-year students in a lecture manner, but most students say, "Control is difficult." It is true that mathematical knowledge and its derivation are required for understanding the classical control theory. Although it is impossible to convert the mathematical expression itself into a tangible form, it is comparatively easy to limit the subject to controlling and manufacturing it in an electric circuit, etc. Therefore, the systematically controlled experiment support system centering on the PID control was built to treat this experiment functionally and visually, by combining basic box-type circuits. We had the fifth-year students manufacture this system and conduct experiments and practices. We introduce the class and report the students' evaluation of the class through questionnaires.
The update of the educational computer system, in Sendai National College of Technology, Hirose was executed in March 2012. The new system adopted the network-boot system similar to the former system aiming at the efficiency improvement of management. In the system, two OS, Linux (Debian) and Windows 7, are available. The system has been operated stably without major problems about one year from the start of operation. The booting time of the user terminal from power on to the login screen had been measured. The booting time of Linux OS was about 30 seconds, while of Windows OS was about 55 seconds. In the simultaneous booting times of 46 terminals in the each room, there was no significant difference in the two rooms. From the results, it can be seen that the network systems and the servers of the network-boot computer system have been configured with the appropriate performance.
