Summary This work presents the discrete‐time stability analysis of a hybrid robust model reference adaptive controller and proportional‐integral (MRAC‐PI) using Lyapunov criterion. The control structure merges classical PI with control, resulting in an strategy, where gains unite both techniques unique it does not require design model, being able to track straightforwardly signal. are updated continuously by modified gradient algorithm regarding action, regulation error, system output. provides constraints, while also demonstrate tendency error residual set, proves boundedness all closed‐loop signals. Furthermore, as is unmodeled dynamics, feasible partially modeled systems. Simulation results real‐world engineering application presented corroborate robustness this show its fast response face critical exogenous perturbations.

With the wide application of hydraulic servo technology in control systems, requirement position performance is greater and greater. In order to solve problems slow response, poor precision, weak anti-interference ability controls, a Kalman genetic optimization PID controller designed. Firstly, aiming at nonlinear such as internal leakage oil compressibility system, mathematical model system established. By analyzing working characteristics valve cylinder parameters are determined. Secondly, algorithm used search optimal proportional integral differential (PID) gain realize accurate valve-controlled displacement system. Under positioning benchmark step signal sine wave signal, optimized compared simulation established by Simulink. Finally, amplitude fluctuations caused GA reduce influence external disturbances, filtering added disturbances on The results show that designed can be better applied Compared with traditional algorithm, improves system’s response speed accuracy; filter good solution for GA-optimized reduces
