Direct Metal Laser Sintering (DMLS) is an additive manufacturing process that utilizes a high-powered laser to build up a metal part by selectively melting thin layers of metal powder. This process is attractive for the manufacturing of parts with complex geometry such as closed centrifugal compressor impellers. DMLS allows closed impellers to be made in a single piece and eliminates the shroud...

This paper presents the experimental results of the real-time performance of modelbased control algorithms. We compare the computed-torque scheme which utilizes the complete dynamics model of the manipulator with the independent joint control scheme which assumes a decoupled and linear model of the manipulator dynamics. The two manipulator control schemes have been implemented on the CMU DD Arm...

A novel hydroturbine governor scheme based on networked control system (NCS) is proposed. The key problem of the scheme rest with the time delay existing in the data communication in NCS as the time delay may be a detriment to governor system stability and may degrade system robustness. In order to guarantee the governor system stable with time delay, the uncertain delay model is modeled as mul...

We present a methodology for designing reference tracking controllers for constrained, discrete-time piecewise affine systems. The approach follows the idea of reference governor techniques where the desired set-point is filtered by a system called the “reference governor”. Based on the system current state, set-point, and prescribed constraints, the reference governor computes a new set-point ...

This article proposes an adaptive coordinated control strategy for the networked AC/DC microgrids (MGs) to enhance frequency and dc voltage stability of system while keeping proper power sharing. First, a based on synchronverter virtual machine (VDCM) converters connecting AC DC MGs is proposed, which consisted governor inertia regulator besides sharing controller. Following, in order performan...

This study focuses on multi-objective optimization of the PID controllers for optimal speed control for an isolated steam turbine. In complex operations, optimal tuning plays an imperative role in maintaining the product quality and process safety. This study focuses on the comparison of the optimal PID tuning using Multi-objective Genetic Algorithm (NSGA-II) against normal genetic algorithm an...

In this study, a conductivity-regulated barrel-type permanent magnet eddy current governor is proposed, and conductor barrel structure scheme consisting of four sections materials with different conductivities presented. The torque equation the equivalent conductivity as covariate was established using separation variable method based on subdomain model, function to obtain speed regulation char...
