The difference in response to electric and hydraulic braking causes sudden changes torque during mode switching. An electro-hydraulic composite system’s dynamic coordination control strategy is proposed under switching conditions. By establishing the model of system (EHB), key factors affecting speed EHB are analyzed, fuzzy controller for pressure regulation brake wheel cylinder designed. At sa...

This paper proposes a new control method applied to an underwater vehicle equipped with a robot manipulator. This control method is based on force control to stabilize the platform when the manipulator works in free or constrained space. The torque produced by the arm on the platform is estimated with a force sensor installed between the base of the manipulator and the vehicle. This allows corr...

A vehicular driveline is the system used to transfer engine torque to the wheels. Resonances in the elastic parts of the driveline are important to handle when control of the engine and the transmission is optimized. Gear shifting by engine control is a new approach for automatic gear shifting with disengaging the clutch replaced by engine control. Resonances are excited in an uncontrolled driv...

We report on the design and analysis of a controller that can achieve dynamical self-righting of our hexapedal robot, RHex. We present an empirically tuned controller that works reasonably well on indoor surfaces, using a hybrid energy pumping strategy to overcome torque limitations of its actuators. Subsequent modeling and analysis yields a new controller with a much wider domain of success as...

Purpose. The main objective of this work is to demonstrate the advantages brought by use space vector modulation technique in direct torque control induction motor. To achieve purpose, two different approaches (with modulation) are proposed and studied from a comparative aspect with each other conventional control. novelty consists employment an Integral-Proportional (IP) speed controller more ...

In conventional direct torque control (DTC) of induction machines, undesirable flux and torque ripples are produced. These occur since non of the selected inverter's voltage vectors are able to generate the exact voltage required to produce the desired changes in the electromagnetic torque and stator flux linkage in most of the switching instances. In addition, when direct torque control is imp...
