The discrete sliding mode control scheme requires only measured outputs - i.e. a subset of the states, and is dynamic in nature. The scheme imposes only minor restrictions on the system theoretic properties and in particular does not require the system to be minimum phase. The controller has been implemented on a real time all vehicle simulator (RTAVS) configured to represent a modern two engined fighter aircraft.

Series compensation is introduced by a controlled switching scheme that changes the transmission line reactance. Switching is implemented according to variable structure control concepts in order to establish a sliding mode operation where oscillations die out very fast. A power system consisting of a synchronous generator, a line reactance with series compensation and an infinite bus is used as a case study. For this basic power system control strategies are shown to pursue: a) sliding mode operation; b) asymptotic stability; or c) asymptotic stability with sliding mode operation. The last strategy assures asymptotic stability for large oscillations and afterwards a fast convergence towards a stable equilibrium state. Simulation tests are then performed for the basic power system, first, for an initial condition and then under a disturbance. The dynamics of a reduced model of a real power system is also studied under a disturbance. The combined strategy, asymptotic stability with sliding mode, shows to be adequate for power system stabilization","PeriodicalId":146618,"journal":{"name":"International Workshop on Variable Structure Systems, 2006.

In particular, such phenomena as nonideal disturbance rejection and non-ideal input tracking are observed in the non-reduced-order model. It is shown that the non-reduced-order model transforms into the reduced one when the parasitic dynamics are removed.

For that reason, a relation relating the tire pressure to the vertical force and the tire vertical deflection is proposed and validated by real measures. Basing on this proposed model, the tire pressure estimation is realized by estimating the vertical force and the tire vertical deflection. The vertical force is estimated using data issued from accelerations sensor. The tire vertical deflection is the difference between its initial radius and its radius when it is in contact with the ground and subjected to the vertical load. The initial radius is given by the constructor, and the other one is identified using a second orders sliding mode observer based on the super twisting algorithm (which observes the non measured states and identifies the effective radius). Simulations are made firstly in the absence of faults, results in this case are compared to the real measures, and secondly in the presence of faults, as an escape (sudden puncture) or a total failure in the tire pressure, in this case results are compared to that of a validated model. The analysis is made on the yaw angle and the yaw rate of the vehicle centre of gravity, the later is compared to a certain threshold which varies with the velocity and the coefficient of friction","PeriodicalId":146618,"journal":{"name":"International Workshop on Variable Structure Systems, 2006.
