The aim of the paper is to propose help for choosing a control strategy to certain specifications. The system under study is an electropneumatic actuator. Different kinds of linear and nonlinear control laws have been developed and experimental results have been analyzed and compared in accordance with appropriate benchmarking. Moreover some new trends are presented. They show the interest of a multi-input control law in terms of stability and energy consumption due to the flatness property.
