Design sliding mode control of fuzzy switching gain for lift-feedback fin stabilizers

There are the problems of larger feedback errors and nonlinear control in conventional fin stabilizer system. Hence, the new lift-feedback control system and sliding mode controller are designed to deal with the nonlinear and uncertain factors of the system. In order to eliminate the chattering of sliding mode control tracking output, the fuzzy control rules are integrated. Then the fuzzy switching gain sliding mode controller is designed. An actual operation 1500t ship is the object, which fin stabilizer system is simulated and verified using fuzzy switching gain sliding mode controller and compared with PID controller. The results show that the designed controller is suitable for lift-feedback control system. As a result, the anti-rolling performance of fin stabilizers is improved.
