Resumen
In this work, we propose a strategy of control of a plant using a wireless sensor feedback. To solve the inherent problems of the wireless sensors the loss of data of the
signal, a predictive controller based on the model (MPC) is used. This technique uses the
basis of 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 level control mesh was developed, 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) work together using the 802.15.4 IEEE protocol and ATMega 328p microcontrollers to close the control mesh, and to implement
the predictive strategy was used in a computer the software of MATLAB computational
simulation. The simulated and experimental results are presented showing a good control
response for packet loss of up to 30%.
