    In order to realize the simple and economic 3rd order LPF using switched-capacitor(SC), we proposed the 3rd order RC LPF using a OP amplifier and realized the 3rd order SC LPF by replacing all the resistors in the RC LPF to SC. The frequency response of SC LPF was compared with the that of RC LPF. As a result, it was found that the response of realized SC LPF is almost similar to that of RC LPF.

    A speed control system of multiple induction motors is presented in this paper. The system consists of a single CSI, several wound retor type induction motors, and the choppers which control the rotor current of motors. Some performance characteristics are studied, and the closed control loop is suggested.

    The optimal control and filtering problems for the systems with the generalized state space model are considered and the generalized Riccati equation is derived. Also the algorithm for the solution of the generalized algebraic Riccati equation is developed and it is shown that the algotithm can be applied to the case where the matrix R is singular or near singular.
