Initially the plane passes through the system representative point in the error state space and then it moves with a constant velocity to the origin of the space. Having reached the origin the plane stops and remains motionless. The plane parameters (determining angles of inclination and the velocity of its motion) are selected to ensure the minimum integral absolute error without violating velocity and acceleration constraints. The optimal parameters of the plane for the system subject to the acceleration constraint are derived analytically, and it is strictly proved that when both the system velocity and acceleration are limited, the optimal parameters can be easily found using any standard numerical procedure for solving nonlinear equations. The equation to be solved is derived and the starting points for the numerical procedure are given","PeriodicalId":146618,"journal":{"name":"International Workshop on Variable Structure Systems, 2006.

A hierarchical control structure is utilized for simplifying the controller design. Uncertain multivariable linear systems are converted into the block controllable form consisting of two subsystems, an input-output subsystem and a stable internal dynamic subsystem. In order to guarantee fast convergence and better tracking precision, a nonsingular terminal sliding mode manifold is proposed for the input-output subsystem. To eliminate the chattering phenomenon, a continuous nonsingular terminal sliding mode control law is designed using the second-order sliding mode approach. Under the proposed controllers, the states of the input-output subsystem can be driven to converge to zero asymptotically and the stability of the zero-dynamics of the system is guaranteed.

In order to design the state estimation, we use the super twisting (second order sliding mode) algorithm. The continuity of the super twisting output injection allows to reconstruct in each step a vector formed by a matrix pre-multiplied by the state vector, all this in a finite time. The sequential application of this procedure finally leads to the obtaining of the state vector which can be represented by an auxiliary state vector plus the equivalent super twisting output injection. It is assumed only that the system has no zeros and the unknown inputs are bounded.

The super-twisting algorithm is employed to attenuate the effect of chattering and obtain continuous control. The structure of the proposed sliding mode controller is appropriate for making the insulin delivery pumps in closed loop control of diabetes.

A higher order Pade approximation to a delay function with a known time delay is used to construct a model of a transformed system without a time delayed output and is employed in a feedback sliding mode control. This model functions as a predictor of the plant states and the plant output, but is of nonminimum phase due to the application of the Pade approximation. The method of the stable system center is used to stabilize the internal dynamics of this plant model, and a control is developed using a sliding surface to allow the plant to track an arbitrary reference profile given by an exogenous system with a known characteristic equation.
