    We present an adaptive torque controller for the full-order nonlinear dynamic model representing an induction motor. The proposed controller requires the full state measurability and compensates for parameter uncertainties in the electrical and mechanical equations. Both the unknown load disturbance and torque to be tracked are assumed to be time-varying. Simulation results are provided to verify ... View full abstract»

    The physics involved in combustion oscillations is complex, and the controller design has frequently been hampered by the lack of reliable models. We make use of a new theory, based on the constant flame speed model of Fleifil et al. (1996), for the nonlinear oscillations of a ducted flame burning in the wake of a bluff-body flame-holder to provide a vehicle on which a robust controller is develop... View full abstract»

    PID control schemes have been widely applied to real control systems, and much research has been carried out on the tuning of PID parameters. Several self-tuning and auto-tuning techniques have been reported for PID control systems with unknown parameters. In this paper, a self-tuning PID control scheme is proposed based on the relationship between the PID control law and the generalized minimum v... View full abstract»

    The problem of identification of a nonlinear vectorial function is studied using an approach based on the rough set and fuzzy logic theories. The rough set theory allows one to obtain a linguistic description of the function, whereas the fuzzy logic theory allows one to generate numerical values of the function starting from its linguistic description. Simulation experiments are shown regarding th... View full abstract»

    We present an alternative approach for the set-point control of the Acrobot. The primary control objective is to regulate the first link at any desired position. A Lyapunov-based control algorithm, which is applicable to both the directly driven and the remotely driven types Acrobot, is proposed. The controller ensures that the first link is asymptotically driven to the desired set-point provided ... View full abstract»

    Design techniques are proposed for active control of buildings under earthquake excitation. For performance, L2 gain (from the ground motion to the controlled outputs) is used as the measure for the disturbance attenuation. The feasibility of the proposed technique can be readily checked through linear matrix inequalities. The validity and applicability of the proposed techniques are il... View full abstract»

    The addition of equality and inequality constraints in generalized predictive control (GPC) strategies switches the classical problem of quadratic cost function minimization into a nonlinear optimization. Some approaches have already been developed, which consider the Lagrange multipliers and gradient optimization. This paper presents the reformulation of GPC under constraints into an adequate for...

Its attitude is controlled by using a small gyroscope. This paper describes the design of the feedback control system which controls the attitude by supporting one of the leg and driving the crotch joints. The basic feedback control system is a one-input tw... View full abstract»

    One of the major challenges in the current fuzzy control research is the automatic design of multiple input controllers for complex nonlinear systems. This paper presents a new genetic-based scheme to treat this issue: the so-called premise learning approach. We propose to search in the input domain for suitable rule premises. The rule premises are coded in a general way allowing AND- as well as O... View full abstract»

    A predictive control scheme based on a blend of receding-horizon plus switching-control ideas is presented for regulating linear plants subject to input saturation constraints. While only local asymptotic regulation can be ensured in general, semi-global exponential regulation is achieved for linear plants which are free of exponentially unstable modes. The overall scheme is based on a fixed finit... View full abstract»
