in this paper, a new smooth second order sliding mode control is proposed. this algorithm is a modified form of super twisting algorithm. the super twisting guarantees the asymptotic stability, but the finite time stability of proposed method is proved with introducing a new particular lyapunov function. the proposed algorithm which is able to control nonlinear systems with matched structured u...

Fire danger rating systems are used to assess the potential for bushfire occurrence, fire spread and difficulty of fire suppression. Typically, fire danger rating systems combine meteorological information with estimates of the moisture content of the fuel to produce a fire danger index. Fire danger indices are used to declare fire bans and to schedule prescribed burns, among other applications...

In this paper we consider a nonlinear feedback control called augmented automatic choosing control (AACC) for nonlinear systems with constrained input. Constant terms which arise from sectionwise linearization of a given nonlinear system are treated as coefficients of a stable zero dynamics. Parameters included in the control are suboptimally selected by extremizing a combination of Hamiltonian...

As Foundation Fieldbus becomes more widely used for the development of process control solutions, the limitations of having a standard, fixed vocabulary of function blocks will become more obvious to control system engineers. To help mitigate this problem, I intend to develop a way to safely specify arbitrary control logic within the dataflow based framework of the Foundation Fieldbus Function ...

Abstract In this paper we argue that financing decisions contribute to the zero-earnings discontinuity. We find a discontinuity in distribution of earnings before tax and special items, but not interest which suggests expense contributes To investigate role discontinuity, further show there was level debt issues around zero contemporaneous with also recent disappearance is coincident issuance d...
