RESUMO:

In this work, we propose a strategy of control of a plant using a wireless sensor feedback. To solve the inherent problem of the wireless sensors of data loss and signal fading, Model Based Predictive Control (MPC) is used. This technique, based on the model of the plant, can estimate the states of the same during the loss of the package increasing the robustness of the system and minimizing the impact on the control mesh. A sensorless level control mesh was developed for a second order plant, emulating a coupled tank system. Simulations and experimental tests were performed to verify the performance of the wireless control system for different packet loss rates. In the implementation, the following components were used: 2.4GHz Transceiver (nFR2401) and ATMega 328p microcontrollers to close the control mesh, and to implement the predictive strategy was used in a computer in the MATLAB environment. The simulated and experimental results are presented showing a good control response for packet loss of up to 30%.
