Adaptive solutions for robust control of electropneumatic actuators

This chapter is focused on the design of robust controllers for electropneumatic actuators. This kind of systems is highly nonlinear, and their dynamics is uncertain due to frictions, uncertainties (especially in mass flow rate), and external perturbation. The use of robust controllers is then strongly recommended in order to get high performances for trajectories tracking or stabilization. This chapter presents very recent robust controllers based on sliding mode theory and adaptive gain. Through the application of control laws mixing high-order sliding mode and adaptive gain, the objective is to show their applicability to a real system and to compare their performances by using similar experimental benchmark.
