A solution is then to develop an adaptive version of the predictive controller for systems with parametric disturbances. This paper presents a direct version of adaptive generalized predictive control, based on the work of Wang and Henriksen. The algorithm is rewritten in an original form minimizing a performance index, using a least-squares type strategy for the controller parameter online identification, including a conditional updating test in the adaptation loop. An application of this structure to an engine drive with an automatic gear box with continuous variations of the reduction ratio is finally developed. The model of this system is derived as a starting point from the well-known two-masses problem. In this study, only the engine speed is measured, the acceleration (variable to be controlled) remains not measurable.","PeriodicalId":108537,"journal":{"name":"Proceedings of the 2000.

More recently, they have been used for fibre fractionation to produce pulp that is more uniform and of higher quality. Careful control is required for the safe operation of pressure screens, and for providing the required flows and level of cleanliness without failure. This is particularly important in fibre fractionation where optimal separation occurs when screens are operated as close as possible to the failure limit. Current control strategies are based on linear univariate control techniques. However, because the process is nonlinear and strongly coupled, univariate linear controllers are likely to perform very poorly when tight control is required. This kind of control requires an accurate model of the system. We describe a nonlinear dynamic model of pressure screens. Different methods were used to estimate the unknown parameters of the model, which was then validated against real data. Furthermore, we propose a simple nonlinear multivariate control strategy based on a static nonlinear model. For performance evaluation, we compare a conventional control strategy to the proposed strategy in simulation, and in pilot plant experiments.","PeriodicalId":108537,"journal":{"name":"Proceedings of the 2000.

In the proposed scheme, inclinometer data are used to compensate for the gyro drift due to roll/pitch perturbation of the vehicle while moving on the rough terrain. Providing independent information about the rotation (yaw) of the vehicle, clino-gyro is used to correct differential odometry adversely affected by the wheel slippage. Position estimation using this technique can be improved significantly, however for the long term applications it still suffers from the drifts of the gyro and translational components of wheel skidding. Fusing this enhanced odometry with the data from environmental sensors (sonars, laser range finder) through Kalman filter-type procedure a reliable positioning can be obtained. This technique has been implemented on-board of an experimental skid-steered vehicle. Obtained precision is sufficient for navigation in underground mining drifts. For open-pit mining applications further improvements can be obtained by fusing proposed localization algorithm with GPS data.","PeriodicalId":108537,"journal":{"name":"Proceedings of the 2000.
