the linear quadratic Gaussian (LQG) control for one-dimensional (1-D) systems has been known to be one of the fundamental and significant methods in linear system theory. However, the LQG control problem for two-dimensional (2-D) systems has not been satisfactorily solved due to their structural and dynamical complexity. In this paper, sufficient conditions for evaluation of the quadratic performance indices of 2-D systems in terms of the system state and control variables are proposed. Using these conditions, systematic design methods for finite horizon and infinite horizon LQG controls of 2-D systems are developed.

Power dc/dc converters are switching circuits controlled by specific PWM regulation. Although they are usually designed for stable operation, many instable state due to complicate bifurcation phenomena have been observed in these decades. To avoid those undesirable operation, a designer must know when and how stability is lost. thus in this paper, we will propose a method to analyze the bifurcation of switching control converters. Many bifurcation curves can be constructed to provide useful information for circuit design and control. Some practical circuits, such as voltage-mode buck converter, current-mode boost converter will be considered.

A new design scheme of direct adaptive neural network controller for a class of nonlinear systems with unknown function control gain is proposed in this paper. the design is based on the principle of sliding mode control and the approximation capability of multilayer neural networks (MNNs). By adopting the adaptive compensation term of the upper bound function of the sum of residual and approximation error, the closed-loop control system is shown to be globally stable, with tracking error converging to zero. Simulation results demonstrate the effectiveness of the approach.

the paper proposes an hybrid Kalman filter integrating a robust and optimal algorithm for the use as an observer in model-varying predictive control (MVPC) of a nonlinear system. Moreover, a position MPC is derived in detail. Even though the proposed approach is quite general, a real case coming from automotive application is studied using computer simulation to demonstrate the effectiveness of the proposed technique. Simulations and results with real data are also discussed.

this paper presents an application of an adaptive fuzzy system for compensating the effects induced by the friction in mechanical system. An adaptive fuzzy system based on fuzzy basis functions is employed, and a bound on the tracking error is derived from the analysis of the tracking error dynamics. the hybrid-controller is a combination of a PD controller and an adaptive fuzzy controller which compensates for nonlinear friction. the proposed scheme is implemented and tested on a DC motor control system. the algorithm and simulations results are described. the results are relevant for many precision drives, such as those found in robot.

A decentralized neuro-controller with feedback error learning is proposed in this paper to deal with robot manipulator tracking problem. the PD + nonlinear (NL) feedback law + robustifying signal ensure global stability while the neural networks are utilized to compensate the decentralized nonlinear terms in the robot manipulator dynamics so that both robustness and good tracking performance are achieved. In addition to the theoretical proof of global stability, the effectiveness of the proposed scheme is also demonstrated by comparing the tracking performance of the neuro-controller for a two-link robot manipulator withthat of the conventional decentralized adaptive controller.

A robust position controller for permanent magnet synchronous motor is described in this paper. First, linear-quadratic method is employed to design the permanent magnet synchronous motor system approximately linear using field-orientation theory. then, the neutral-network technique with adaptive learning rates is implemented to make the system insensitive to the uncertainties including parameter variations and external disturbance in the whole control process. Finally, the experimental results verify that the dynamic behaviors of the proposed control systems are robust with regards to uncertainties.

the problem of adaptive robust tracking and model following is considered for a class of linear dynamical systems with multiple delayed state perturbations, time-varying uncertain parameters, and external disturbance. A class of adaptive output feedback controllers is proposed for robust tracking of dynamical signals. Based on the strictly positive realness of the nominal system, it is shown from the Kalman-Yakubovitch lemma that the proposed adaptive robust output feedback tracking controller can guarantee the zero-error tracking.
