Abstract
The QLQG/LTR control method is applied to a nonlinear system with Coulomb friction which has a non-Gaussian nature. It is shown that the non-Gaussian nature degrades the effectiveness of the QLQG/LTR design method. Thus, a method for alleviating this problem is proposed. It is the QLQG/LTR control method with a modified model based compensator which can consider the non-Gaussian nature of nonlinear systems. The computer simulation results show that the responses of this nonlinear control system are relatively insensitive to the imput magnitude even if there exist a hard nonlinearity and a non-Gaussian nature in the plant.
