Research of a Control Valve Characteristics Test
Control valves are commonly found in modern process plants. The control valve reliability is critical to the control quality and safety of a plant. Whether a control valve meets the challenge of the control requirement depends on its response characteristics. To obtain the characteristics of the control valve, an experiment test system is developed to assess the performances of the control valv...
متن کاملTorque Control of Brushless Direct Current Motor Drives Using Single Current Sensor with High Reliability
Due to the simple structure, high torque density, low maintenance, and high efficiency, brushless direct current (BLDC) motors are widely used in automation and industrial applications. A control strategy based on single current sensor is proposed for a four-switch three-phase BLDC motor system to lower cost and improve reliability. The whole working process of the BLDC motor is divided into si...
متن کاملEnhanced Predictive Current Control of Three-Phase Grid-Tied Reversible Converters with Improved Switching Patterns
A predictive current control strategy can realize flexible regulation of three-phase grid-tied converters based on system behaviour prediction and cost function minimization. However, when the predictive current control strategy with conventional switching patterns is adopted, the predicted duration time for voltage vectors turns out to be negative in some cases, especially under the conditions...
متن کاملMultivariable-PI-Based dq Current Control of Voltage Source Converters With Superior Axis Decoupling Capability
This paper presents a linear direct–quadrature current control strategy for voltage source converters (VSCs) in a rotating reference frame (RRF). The described method is based on multivariable-proportional–integral (PI) regulators and provides fast dynamics and a zero steady-state error. Contrary to the well-known conventional PI-based control strategies in RRFs, the presented method provides p...
متن کاملGeneralized Average-current-mode Control of Single-phase Ac-dc Boost Converters with Power Factor Correction
The dissertation presents a generalized average-current-mode control technique (GACMC), which is an extension of the average-current-mode control (ACMC) for single-phase ac-dc boost converters with power factor correction (PFC). Traditional ACMC is generalized in a sense that it offers improved performance in the form of significant reduction of the current control loop bandwidth requirement fo...
