this paper proposes an approach for the minimum time swing upof a rotary inverted pendulum. our rotary inverted pendulum is supported bya pivot arm. the pivot arm rotates in a horizontal plane by means of a servomotor. the opposite end of the arm is instrumented with a joint whose axisis along the radial direction of the motor. a pendulum is suspended at thejoint. the task is to design a contro...

In this paper, a robust tracking control method for automatic take-off and trajectory tracking of a quadrotor helicopter is presented. The designed controller includes two parts: a position controller and an attitude controller. The attitude controller is designed by using the sliding mode control (SMC) method to track the desired pitch and roll angles, which are the output of position controll...

This work presents a nonlinear control strategy for magnetically coupled multiport dc-dc converter aimed at automotive applications. First, behavioural dynamic model, based on averaging the power flowing among ports, is derived. Then, algorithm, feedback linearization techniques, proposed. Essentially, controller ensures decoupling and linear behaviour thanks to transformation of state variable...

OBJECTIVE To verify the sensitivity of the conventional subtests of the Behavioral Inattention Test (BIT) in the diagnosis of hemineglect after stroke. METHOD One hundred and two patients with cerebral infarct or hemorrhage were prospectively evaluated. In 22, hemineglect was diagnosed using standard BIT criteria. The frequency of hemineglect using 6 commonly used screening subtests of this b...

In the previous article we have introduced an isotropic algorithm for temporal sequence learning (ISO-learning). Here we embed this algorithm into a formal nonevaluating (“teacher-free”) environment which establishes a sensor-motor feedback. The system is initially guided by a fixed reflex reaction which has the objective disadvantage that it can only react after a disturbance has occurred. ISO...

OBJECTIVE To determine whether visual evoked magnetic fields (VEFs) elicited by right and left hemifield stimulation differ in patients with unilateral spatial neglect (USN) that results from cerebrovascular accident. METHODS Pattern-reversal stimulation of the right and left hemifield was performed in three patients with left USN. Magnetoencephalography (MEG) was recorded using a 160-channel...

Because of extreme local saturation at pole tips of excited phase and uncircular shape of rotor and stator, a Swithed Reluctance Motor (SRM) does not have a simple and accurate mathematical model. Therefore, the output control of this motor requires a robust controller which is not based on an accurate model of the process. Fuzzy controllers, to some extent, will satisfy these requirements. Tet...
