“…The design algorithms of polyhedral sets and the control law computations are described in detail in [20,21]. In the simplest case the control law can be calculated by searching all regions one after another until the active one is found and subsequent implementation of the control law in accordance with (23).…”

Such requirements results in an increasingly higher use of the properties and strength of construction materials. Therefore, in a growing number of drives one can observe finite stiffness of couplings between a drive and machinery. This problem was initially considered in the heavy industry in various types of machines, such as: rolling mills [13], conveyor belts [10] Various methods are used in the control of vehicle speed or the location of drives with an elastic coupling, starting with simple ones based on a PI controller tuned with account for coupling elasticity [22], to the introduction of additional feedbacks from one to a few state variables to such a controller, a detailed overview of such solutions can be found in [17]. Some other control systems use adaptive control. Such methods as fuzzy sliding mode control and neural control [3,7], as well as vortex control [14] can be distinguished here, this group of methods ensures good oscillation attenuation and it is additionally characterised by high resistance in the case of wrongly determined drive parameters. Another approach to adaptive is presented in [8,18], here a superior system was used to retune controller setting, it continuously reproduces the unknown and variable parameter. Yet another, not so common, is the sliding mode control [9].In the case drives with an elastic coupling, the major challenge faced by the control system is the attenuation of the oscillation of electro-mechanical state variables. However, another issue which appears in the discussed group of drives is the limitation of the torsional torque amplitude in such a way that the lives of mechanical couplings can be extended, which improves the reliability of the whole drive system. However, the above described methods do not allow to introduce the restriction of the values of state variables (torsional torque) in a simple way. The only restricted values is the set electromagnetic torque (control signal). In such systems the only way to limit the amplitude of internal state variables is weakening the dynamics of the whole system. Another approach which allows to introduce the value restrictions of a selected state variable is using the cascade control structure in which a separate, subordinate control loop is formed. Then it is possible to restrict such state variable [16]. One of the methods allowing to introduce the restrictions of the values of state variables is predictive control. This method allows to introduce limitations as early as the ...

Abstract-The paper presents an application of unscented Kalman filters to an automotive electronic throttle device. The motivation of this study is on estimating the position of the throttle device when measurements of position are inaccessible, e.g., due to failures in the sensor of position. In this case, an external wattmeter is connected in the circuitry to measure the power consumed by the throttle, and this information feeds unscented Kalman filters to produce the estimation for the position. Experimental data support the findings of this paper.Note to Practitioners: Abstract-Almost all of the brand-new vehicles based on spark-ignition combustion engines have an electronic throttle valve to control the power produced by the engine. The electronic throttle has a unique sensor for measuring the position of the throttle valve, and this feature can represent a serious problem when the sensor of position fails. As an attempt to prevent the effects of a failure from such sensor, we present an algorithm (unscented Kalman filter) combined with the use of an additional sensor, a wattmeter. The wattmeter is detached from the throttle's structure but is arranged so as to measure the electric power consumed by the throttle. Measurements of the power consumption then feed the unscented Kalman filter-this filter then produces an estimation of the position of the throttle valve. Experimental data illustrate the practical benefits of our approach.

This note considers the energy optimal trajectory control design approach. Solving the exact optimal solution is challenging because of the nonlinear and switching cost function, and various constraints. The minimum principle is applied to establish piecewise necessary optimality conditions. An approximate optimal control is proposed to circumvent the difficulty due to the nonlinearity of the cost function. Simulation is performed to illustrate the generation of the approximate optimal trajectory.
