Sliding mode (SM) and Proportional-integral-derivative (PID) controller are implemented for Buck converter in a continuous conduction mode. A closed-loop controller system is implemented and goes through the transient time response of buck converter. Sliding mode controller is worked as robust controller and can be used to reduce the Delay time and settling time of the system. In power drives c...

In a typical disk drive servo system, two or more types of controllers are used for track seeking, track following, and track settling modes. This leads to the problem of mode switching among these controllers. We present in this paper a unified control scheme, the discrete-time composite nonlinear feedback control, which can perform all the above functions in hard disk drive (HDD) servo system...

In this paper a multistage fuzzy controller is designed and implemented on the ball and beam system which is a well-known benchmark in the control area because of its nonlinear, unstable non-minimum phase behavior. The most important property of the proposed controller is its simplicity whiles it fully mimics human’s actions for controlling this system. In comparison to classical controllers su...

This paper presents an Intelligent control based fuzzy logic for Sensorless speed control of induction motor drive. The proposed scheme used indirect vector control with fuzzy logic controller which gives optimal condition for maximum torque both in steady state and transient condition and has ability to plan via decomposition of a complex task into manageable subtasks and it has auto tuning pr...

This paper presents the results obtained when using a multi-objective genetic algorithm for tuning the gains of a PID controller for position control. To evaluate this approach, the plant to control is a robot manipulator with 2 degrees of freedom (DOF), which has the following characteristics: The dynamic model is not linear, it is a system of multiple input and multiple output (MIMO) and it h...

To facilitate human assembly tasks, Robonaut 2 is equipped with a dexterous, compact hand featuring fingers driven remotely by tendons. This work outlines the force-control strategy for the fingers, which are actuated by an “n +1” tendon arrangement. Existing tendon-driven fingers have applied force control through independent tension controllers on each tendon, in other words, in the tendon sp...

We address an active way of depth estimation using the mechanical degrees of freedom of a stereo vision system. A depth map will be computed in an action-perception cycle by using the control of gaze and vergence of the active system iterately. We apply a phase-based approach to compute disparity maps on diier-ent resolutions. Due to the phase-based approach sub-pixel accuracy in disparity esti...

We report learning measurements from a system composed of a cascadable learning chip, data generators and analyzers for training pattern presentation, and an X-windows based software interface. The 32 neuron learning chip has 496 adaptive synapses and can perform Boltzmann and mean-field learning using separate noise and gain controls. We have used this system to do learning experiments on the ...

A rail-to-rail class-AB CMOS buffer is proposed in this paper to drive large capacitive loads. A new technique is used to reduce the leakage power of class-AB CMOS buffer circuits without affecting dynamic power dissipation .The name of applied technique is LECTOR, which gives the high speed buffer with the reduced low power dissipation (1.05%) and reduced area (2.8%). The proposed buffer is si...
