This paper proposes an advanced position-tracking control approach, referred to as an integrated intelligent nonlinear controller, for a pneumatic artificial muscle (PAM) system. Due to the existence of uncertain, unknown, and nonlinear terms in the system dynamics, it is difficult to derive an exact mathematical model with robust control performance. To(More)
This paper presents an accurate position control for a pump-controlled electro-hydraulic actuator (EHA) using time-delay estimation (TDE). The TDE technique is used to estimate nonlinear terms of EHA, which is a third order nonlinear system. The measured signal of linear encoder, and pressure of the EHA are used to implement the TDE technique. The(More)
In this paper, an advanced nonlinear method - adaptive output feedback (AOF) controller - is presented for position tracking control problem of a pump-controlled Electro Hydraulic System (EHS). The system uncertainties including uncertain parameters and external disturbances are covered by an adaptive law while all nonlinearities are compensated by a(More)
In this paper, an advanced controller is presented for position tracking control and minimizing control energy of an electro-hydraulic system. An index function is first formulated for the closed-loop performance. The optimal control input is then calculated based on the Taylor series expansion of the index function. For providing information to the control(More)
In this paper, an adaptive nonlinear controller is presented for position tracking control problem of a pump-controlled Electro Hydraulic System (EHS). The system nonlinearities are compensated by an advanced backstepping-based technique while all uncertainties including uncertain parameters and external disturbances are estimated directly from the state(More)
