This paper presents the development of a prototype of a system for remote data acquisition of environmental variables in the Amazon Forest called GETFOREST. The system performs all the functions of a Datalogger and has the task of analyzing behavior in a forest reserve by an intelligent agent, which contains expert systems of the patterns related to environmental variables of temperature, relative humidity and dew point. The sensor hardware is composed by a computational embedded unit that contains an analog/digital data acquisition in wireless communication interfaces.
Abstract. This paper addresses the problem of achieving gain equalization on all input-output channels of multivariable square dynamic systems which have a pole at the origin. A mathematical procedure based on linear transformations is proposed to extract the integrator associated with this pole to the outside of the system in a specific output channel. The order of the system model is then reduced, and the removed integrator can be joined with other new integrators that are added to the others output channels of the system in order to accomplish the desired gain equalization. A 5th order, 3I3O system (three inputs and three outputs) is considered as an example, for which a reduced order LQG/LTR controller is also designed.
