Electromechanical Servo Systems Robust Control Synthesis Under Non-Gaussian Random External Disturbances

Stochastic robust control by the electromechani-cal servo systems under non-Gaussian random external disturbances based on the anisotropic theory of stochastic robust control was synthesized. The solution of the problem of synthe-sis of an anisotropic optimal controller in the state space is based on the solution of three cross-coupled algebraic Riccati equations, the Lyapunov algebraic equation and the equation with respect to the logarithm of the determinant of a positive definite matrix. The results of modeling and experimental studies of stochastic robust two-mass electromechanical servo systems under non-Gaussian random external disturbances are given. With the help of synthesized robust stochastic control-lers, it is possible to improve of quality indicators of two-mass electromechanical servo system in comparison with the system with standard regulators that it is established based on the results of modeling and experimental studies.
