An Adaptive Optimal Control Algorithm for Jet Pipe Electro-hydraulic Servo Valve

In this paper, an adaptive optimal controller design method is proposed for the jet pipe electro-hydraulic servo valve. By establishing the dynamic model of the electro-hydraulic servo valve, the state variables and control variables are selected and transformed into the solution of the optimal control problem. Then based on adaptive dynamic programming (ADP) technology, which uses the state and online input information to iteratively solve the algebraic Riccati equation, the optimal control problem of the electro-hydraulic servo valve is solved. Finally, a simulation is given to demonstrate the effectiveness of the method in solving the optimal control problem of the electro-hydraulic servo valve of the jet tube.
