Vahid Behnamgol; Ahmadreza Vali; ali mohammadi

Volume 11, Issue 2 , September 2018, , Pages 1-10

Abstract
  Nonsingular terminal sliding mode (NTSM) guidance for intercepting the desired line of sight (LOS) angle in terminal phase is proposed in this paper. In order to satisfy the predefined LOS angle and to intercep into target, a nonsingular terminal sliding variable is introduced. In reaching phase, in ...  Read More

Lyapunov-basedAdaptive SmoothSecond-order Sliding Mode Guidance Law with Proving Finite Time Stability

Vahid Behnamgol; Ahmadreza Vali; ali mohammadi; َAshknaz Oraee

Volume 11, Issue 2 , September 2018, , Pages 33-39

Abstract
  A new adaptive smooth second-order sliding mode control is proposed for uncertain nonlinear systems in this paper. The finite time stability is proved using a Lyapunov technic. The proposed controller consists of an adaptive term equal to the uncertainty in finite time. This algorithm is used to design ...  Read More

Performance and Stability Investigation of a line of sight based Guidance System in the Presence of Measurement Noise

Valiollah Ghaffari; Paknoosh Karimaghaee

Volume 11, Issue 1 , June 2018, , Pages 31-40

Abstract
  Usually vehicles are equipped with guidance algorithm based on line of sight (LOS) angle. In this way, some measurements like target acceleration, LOS rate, and closing velocity are provided for the guidance algorithm. The noise effect on the guidance loop would be neglected when the variance of the ...  Read More

A New Backstepping Sliding Mode Guidance Law Considering Control Loop Dynamics

Vahid Behnamgol; Ahmad Reza Vali; Ali Mohammadi

Volume 8, Issue 4 , January 2016, , Pages 9-17

Abstract
  In this paper, a new procedure for designing the guidance law considering the control loop dynamics is proposed. The nonlinear guidance loop entailing a first order lag as the control loop dynamics is formulated. A new finite time and smooth backstepping sliding mode control scheme is used to guarantee ...  Read More

New Approach in Guidance Law Design Based on Finite-Time Partial Stability Theorem

Tahere Binazadeh; Mohammad Hossein Shafiei; Elham Bazregarzadeh

Volume 8, Issue 1 , April 2015, , Pages 1-7

Abstract
  This paper presents a novel approach in design of missile guidance law against highly maneuvering targets. This approach is based on the principles of partial stability and finite-time stability (finite-time partial stability). Also, it is shown that the designed guidance law is in conformity with a ...  Read More
