The control systems typically use the conventional PID (Proportional, Integral, Derivative) controller to control the direct current (DC) voltage [1]. The obtained control results are relatively well when PID controller is applied, but the design parameters are not absolutely precise and sensitive to the changes of system parameters. The PID controller is used to control the frequency of three-phase...
We develop a finite volume method on a geometrically refined mesh to effectively treat the boundary layer singularity of the solutions to the boundary value problem of fractional differential equations. We further exploit the structure of the stiffness matrix to develop a properly modified fast conjugate gradient method for the efficient solution of the linear algebraic system. The fast method has...
The problem of joint input and state estimation is discussed in this paper for linear discrete-time stochastic systems. By minimizing an objective function of weighted least squares estimation with respect to the states and unknown inputs, a recursive filter approach referred to as General Kalman filter with unknown inputs (GKF-UI) is obtained. It is shown that the proposed GKF-UI approach covers...
A novel real-time receding horizon tracking control (RHC) strategy is presented for nonlinear discrete-time systems with quadratic criteria for fast controller response. The control law is derived by using the receding horizon concept from the optimal tracking problem. First, the original problem is reduced to an equivalent optimal regulator problem for an offline system by augmenting the state variables...
An optimal regulator is presented for a nonlinear discrete-time system with input delay and a quadratic criterion. First, the original problem is reduced to the nonlinear-quadratic regulator design for a system without delays by an extended Artstein model reduction approach. Then, An iterative process is proposed to find a solution sequence of the nonlinear two-point boundary value (TPBV) problem...
