In order to investigate the nonlinear systems, we introduce different nonlinear characteristics into a given linear unit feedback system and utilize MATLAB/Simulink toolbox to simulate the output response of the step signal of the system. Simulation results show that the introduction of nonlinear links affects the stability of the control system. The dead zone nonlinear link decreases the equivalent gain of the system under the action of large signal, and the system loses the closed-loop control under the action of deep saturation. Saturation nonlinear link can make the system tend to be stable, but it reduces the amplification factor and the steady-state accuracy. Saturation nonlinear link can make the system tend to be stable, but it reduces the amplification factor and the steady-state accuracy. These nonlinear characteristics can also be used in the analyzing of the nonlinear characteristics in the multidisciplinary coupled software system or other complex systems. |
