Designing a Generic, Software-Defined Multimode Radar Simulator For FPGAs Using Simulink HDL Coder and Speedgoat Real-Time Hardware

This publication focuses on the implementation and testing of a fully-parameterized radar signal processing prototype. A Speedgoat Performance machine with two Simulink-Programmable FPGA I/O modules IO342 are used for the implementation of a radar signal processing design containing several common waveforms and tunable parameters and a radar scene generator for delay, doppler, and amplitude measurement.This setup helped increase the simulation fidelity while reducing the time to test.

Design, Simulation and Hardware-in-the-Loop (HIL) Testing of an Electric Scooter Powertrain

This publication focuses on an algorithm to control a brushless DC motor. A Speedgoat performance machine runs a digital twin of the motor on both the CPU and the FPGA-based I/O module IO334 and is connected via the analog channels to the controller, an MCU by Texas Instruments. With this HIL setup, the performance of the control algorithm was tested. 

A Self-Tuning Robust Control System for Nonlinear Simulation

A transfer system is used to enforce the interface interaction between computational and physical substructures in a real-time hybrid simulation. A model-based, multilayer nonlinear control system is developed to accommodate extensive performance variations and uncertainties in a physical substructure. This work aims to extend the application of real-time simulation to investigating failure, nonlinearity, and nonstationary behavior.

Topological Analog Signal Processing

Researchers at the Swiss Federal Institute of Technology in Lausanne (EPFL) used a Speedgoat Performance real-time target machine and a high-speed analog IO131 module to validate an acoustic topological equation solver experimentally. The setup allowed them to demonstrate the robustness of analog signal processors (ASP) and is an essential step towards a new generation of ultrafast all-optical ASPs.

Robust Switching Control Method to Achieve Tokamak-Shaped Plasma

A robust switching control method with state vector matching and a novel approach for the feedback system simulation are presented in this paper. First, the plant model reconstructs plasma equilibria from experimental data and calculates plasma shape changes. Then, the control system is discretized and run on a high-speed computer for experiments on a real-time testbed.

Robust switching control in the Feedback for Tokamak Plasma Shape

A hierarchical robust switching control method with state vector matching is proposed. The plasma shape is controlled via a magnetic field at X-point and poloidal fluxes on the plasma separatrix. Using a combination of advanced reconstruction code with isoflux control leads to high performance.

Validation of a Servo-Hydraulic Model Coupled with a Nonlinear System

In the study, a controllable canonical physics-based model of a servo-hydraulic actuator coupled with a nonlinear physical system form is validated for position tracking control purposes. This is done by designing and fabricating a nonlinear device to exhibit various nonlinear force-displacement profiles depending on the initial condition and the type of materials used as replaceable coupons.

Real-Time Force Control for a Servo-Hydraulic Actuator Systems

Servo-hydraulic actuators have been widely used but existing control algorithms face some issues. This paper introduces a new real-time force control method utilizing the adaptive time series (ATS) compensator and compliance springs. Unlike existing approaches, the proposed force control methods do not require the structural modeling of a test structure, making it easy to be implemented primarily for nonlinear systems.

Active Magnetic Bearing for Ultra-Precision Flexible Electronics Production System

Roll-to-roll printing of flexible electronics on continuous plastic films could enable the production of flexible electronics at high speed and low cost. However, rolling element bearings cannot be deployed because of the precision requirements. Instead, active magnetic bearings (AMB) with optical positioning encoder feedback are used.
