Sekhavat, P., Auteur ; Sepehri, Nariman ; Q. Wu, Auteur |Every manipulator contact task that begins with a transition from free motion to constraint motion may exhibit impacts that could drive the system unstable. Stabilization of manipulators duringthis transition is, therefore, an important issue in[...]

Mark Karpenko, Auteur ; Sepehri, Nariman, Auteur |This paper documents the design of a low-order, fixed-gain, controller that can maintain the positioning performance of an electrohydraulic actuator operating under variable load with a leaking piston seal. A set of linear time-invariant equival[...]

Abo-Shanab, R. F., Auteur ; Sepehri, Nariman, Auteur |This paper describes the development of a simulation model for studying the tip over stability of a typical heavy-duty hydraulic log-loader machine. The model takes into account the dynamics of (i) the base that can potentially rock back and for[...]

Goharrizi, Amin Yazdanpanah, Auteur ; Sepehri, Nariman, Auteur |This paper describes the application of wavelet transform (WT) to detect internal leakage in hydraulic actuators, caused by seal damage. The method analyzes the pressure signal at one side of the actuator in response to periodic step inputs to t[...]
