Designing a robust tracking control for a non-linear MIMO system with uncertainty is one of the most complicated control problems. In this paper, sliding mode changed to non-linear controllable canonical form by input-output linearization. This, sliding surfaces can be defined in a way that we can de-couple equations and indicate the sliding conditions of multi-variable controller system. The u...

In this paper a laminar flow of water on an ice layer subjected to a slip condition is considered numerically. The paper describes a parametric mathematical model to simulate the coupled heat and mass transfer events occurring in moving boundary problems associated with a quasi steady state steady flow process. The discretization technique of the elliptic governing differential equations of mas...

In this paper, an algorithm is developed to reject time and spatially varying boundary disturbances from a multi-dimensional Kirchoff plate via boundary control. The disturbance and control input are assumed to be matched. The active disturbance rejection control (ADRC) approach is adopted for developing the algorithm. A state feedback scheme is designed to estimate the disturbance based on an ...

We are here concerned with an optimal control problem for a state equation of parabolic type on a bounded real interval, which for convenience we take equal to [0, π]. We stress the fact that we consider Neumann boundary conditions in which the derivative of the unknown is equal to the sum of the control and of a white noise in time, namely:  ∂y ∂s (s, ξ) = ∂2y ∂ξ2 (s, ξ) + f(s, y(s, ξ)...
