Abstract:
This paper describes the development and tests of a software which was projected to support the work of designing and testing dedicated embedded controllers. It was developed to accomplish two main features: helping to model the physical system to be controlled; and helping to easily implement and test a proposed controller to be applied to the physical system. Two practical applications are presented. The first one is the design of a temperature controller for a new version of a water caloric stimulator named E96, which has as main requirement fast and accurate temperature response with no overshoot. The second one is also a caloric stimulator, but the transfer media is air instead of water. Those equipments help otorhinolaryngologists in electronystagmography exam. Details on the caloric stimulators hardware and software, the proposed controllers and the results, are presented. The software was considered functional for the proposed applications.
