This paper presents the application of predictive control to drug dosing during anesthesia in patients undergoing surgery. The performance of a generic predictive control strategy in drug dosing control, with a previously reported anesthesia-specific control algorithm, has been evaluated. The robustness properties of the predictive controller are evaluated(More)
In this paper it is investigated the trajectory tracking control of a wheeled mobile robot using a laser rangefinder sensor to estimate the robot position and orientation (posture). This technique is compared with the conventional odometry method where the encoders data are used for posture estimation. The paper also presents the description of the robot as(More)
This paper presents a dead-time compensation structure able to deal with stable and unstable multiple delay single input single output (SISO) systems. The proposed method aims to simplify the primary controller by replacing it for FIR filters placed at the feedback path. Such modification reduces the total number of parameters to be tuned which facilitates(More)
The lifetime of a battery depends mainly on the operating temperature. Thus, this paper proposes a low cost refrigeration system applied to batteries temperature control. In the proposed system, Peltier modules (thermoelectrical devices, which uses the Peltier effect for heat exchange) are used to refrigerate the system. In addition are compared the(More)
This paper presents the application of predictive control to drug dosing during anesthesia in patients undergoing surgery. A single-input (Propofol) singleoutput (Bispectral index) model of the patient has been assumed which includes the variable dead time caused by the measurement of the Bispectral index. A set of 12 patient models were studied.(More)
This paper proposes a simplified tuning strategy for the multivariable filtered Smith predictor. It is shown that offset-free control can be achieved with step references and disturbances regardless of the poles of the primary controller, i.e., integral action is not explicitly required. This strategy reduces the number of design parameters and simplifies(More)
This paper presents a constrained horizon predictive controller based on a filtered Smith predictor structure (CHSPPC). The proposed algorithm is particulary appropriate to control dead time systems as it exhibits better robustness than others, specially when errors in the dead time estimation are considered. The tuning of the controller parameters includes(More)
