“…Furthermore, when the plant has integrators, the plant output may be affected by the input-side disturbance. 25,26 The method proposed in this study is not affected by the input-side disturbance or by the variation of the plant parameters. The manipulated variable consists of the plant parameters and the robust gain matrix, which is obtained by the switching function and is independent of the plant parameters.…”

This study presents a model-following positioning control system based on modified sliding mode control. In the proposed method, a robust gain matrix prevents the dependence on the plant parameters by applying the switching function to an error dynamics equation. Simulation studies are applied to a nominal plant with stable and unstable terms, and a plant with a modeling error and an input-side disturbance. Simulation and experimental results indicate the effectiveness of this method in determining a robust gain matrix. The proposed method further demonstrates positioning control with superior performance.

This paper describes and demonstrates a model-following control system that is based on a switching function where an optimal gain matrix is determined by the LQR method. In our proposed method, the optimal gain matrix is derived such that it does not depend on the plant parameters. Simulation results show various cases including the nominal plant and the plant with a modeling error. The experimental study is also performed using a DC motor. The simulation and experimental results show that the proposed method has superior effectiveness.

“…Though the input signal F ref has single frequency of 10 Hz, the output signal F mass includes higher mode, which originate for the nonlinear spring characteristics, has appeared [3]. Therefore, the LMM-based control object with the nonlinear spring characteristic is not able to control based on the linear control method due to the higher order harmonics [5][6][7][8][9][10].…”

In this paper, a controlled oscillation using the levitation mass method (LMM) for material with nonlinear viscoelasticity is proposed. Since LMM is a very accurate and efficient method of measuring a varying force, it has a possibility to apply to the material tester. For LMM, system identification process is introduced to grasp the nonlinear components of the restoring force. The process consists of the experiment and frequency analysis for higher modes which originate for the nonlinear restoring force. The input signal is then derived based on the identification results. By adding the proposed identification process to LMM, the arbitrary waveform of the force can be investigated even in the open-loop excitation. The effectiveness of the proposed oscillation method is verified through the LMM-based experiments.
