The dynamics of a robotic hand is highly non-linear and needs nonlinear feedback control strategies for its functionality. One of the highly promising and rapidly developing techniques for nonlinear, optimal, feedback control is based on the State Dependent Differential Riccati Equation (SD-DRE), also commonly called SDRE. In this technique, an analytical approach is used to transform the original...
DC motors are widely used in industrial applications. Controlling of DC motor is a great challenge for control engineers. Precise equations describing DC motors are nonlinear. Accurate nonlinear control of the motion of the DC motors is required. In this paper, a novel online technique for finite-horizon nonlinear tracking problems is presented. The idea of the proposed technique is the change of...
A number of computational techniques have been offered for estimation of unmeasured states in nonlinear systems. Most of these techniques rely on applying the linear estimation techniques to the linearized systems, which can be effective only in the neighborhood of the operating point. This paper presents a new efficient approximate online technique used for finite-horizon nonlinear stochastic regulator...
The majority of homing guided missiles, uses gimbaled seekers. The equations describing seeker gimbal system are highly nonlinear. Accurate nonlinear control of the motion of the gimbaled seeker through the attached DC motors is required. In this paper, an online technique for finite-horizon nonlinear tracking problems using Finite-Horizon State Dependent Riccati Equation (SDRE) is presented. The...
In this paper, an online technique for finite-horizon nonlinear stochastic tracking problems is presented. The idea of the proposed technique is to integrate the Kalman filter algorithm and the State Dependent Riccati Equation (SDRE) technique. Unlike the ordinary methods which deal with the linearized system, this technique will estimate the unmeasured states of the nonlinear system directly, and...
