This paper deals with a design and implementation of an incubator temperature control system. This system is composed of the incubator, a PLC-based PID controller, HMI (human-machine interface), DC dimmer as actuator and an NTC temperature sensor. A mathematical model of the incubator system with appropriate sensor and drives is derived through identification process based on step responses. Its model...
The authors have studied a linear pulse motor-driven artificial heart (LAH-S91) with left and right blood pumps, with the goal of implantation and use. The requirements on the LAH of small size and high-thrust actuators pose challenging problems for the evaluation method. The results of performance tests of the LAH-S91 are: 1). Driving characteristics of the LAH-S91 were calculated using a cardiovascular...
