“…Furthermore, impedance and resonant frequency are dependent on these properties. In [33], three different inductor circuit models are presented with varying complexity and ability to reproduce real inductor behavior. The intermediate model, which is shown in figure 2, was sufficient for analysis of magnetorquers produced for the FORESAIL-1 satellite.…”

Magnetorquer based attitude control system capable of attaining high spin rates and precise pointing control is required for a 3U CubeSat satellite FORESAIL-1. The satellite, developed by Finnish Centre of Excellence, needs to maintain a spin rate of 24 • /s and precise pointing of the spin axis toward the Sun for the particle telescope instrument, as well as to reach 130 • /s spin rate for the deployment of the plasma brake. Mission requirements analysis and attitude system requirements derivation are presented, followed by actuator trade-off and selection, with detailed design of the complete attitude control system, including air-cored type of magnetorquer actuators and their drivers, made of H-bridge and filtering components. The design is based on several theoretical and practical considerations with emphasis on high power efficiency, such as effects of parallel and serial magnetorquer connections, modelling the magnetorquers with equivalent circuit models for finding of suitable driving frequency and extrapolation methods for efficient dipole moment usage. In-house manufacturing process of magnetorquers, using a custom 3D-printer setup, is described. Lastly, the testing and verification are performed, by measuring the performance of the manufactured hardware, circuit simulations and attitude control simulations. It is shown that the manufactured attitude control system fulfils all system requirements. Simulations also confirm the capability to satisfy mission requirements.

The Qucs/QucsStudio and Qucs-S simulators share a common graphical user interface which has slowly evolved into an interactive platform for drawing circuit schematics, controlling simulation and displaying simulation output data and measured device/circuit parameters/properties. This interface acts as a window for accessing circuit simulation software and is in many ways similar to the "White-Boards" that are popular among scientists and engineers for recording ideas when "brainstorming" circuit design or analysis problems. This paper outlines the evolution of the Qucs device modeling and simulation "white-Board" from concept to working media over the fifteen year period that Qucs, QucsStudio and Qucs-S have been under development. The operation of a number of the "White-Board" features are introduced with a compact tunnel diode model and the simulation data obtained from tests using the QucsStudio and Qucs-S software packages.

“…Qucs release 0.0.19S provides for the first time a set of modelling and simulation tools built around the well‐established Qucs graphical user interface, the Qucs qucsator simulation engine, the Qucs EDD and radio frequency equation‐defined devices , the Qucs/ADMS Verilog‐A ‘turn key’ component modelling system (including a new Verilog‐A synthesizer), the Ngspice and Xyce ©circuit simulators (including a new SPICE netlist synthesizer) and the Qucs and Octave numerical analysis data visualization software. An overview of the individual sections of the Qucs‐0.0.19S software package are presented as block diagrams in Figure , where diagram (a) illustrates the overall structure of the modelling system and the data flow from initial physical model specification to the visualisation of simulation data, and diagram (b) shows a simplified set of the modelling blocks and the data flow associated with new model development.…”

Since the introduction of SPICE non-linear controlled voltage and current sources, they have become a central feature in the interactive development of behavioural device models and circuit macromodels. The current generation of SPICE-based open source general public license circuit simulators, including Qucs, Ngspice and Xyce©, implements a range of mathematical operators and functions for modelling physical phenomena and system performance. The Qucs equation-defined device is an extension of the SPICE style non-linear B type controlled source which adds dynamic charge properties to behavioural sources, allowing for example, voltage and current dependent capacitance to be easily modelled. Following, the standardization of Verilog-A, it has become a preferred hardware description language where analogue models are written in a netlist format combined with more general computer programming features for sequencing and controlling model operation. In traditional circuit simulation, the generation of a Verilog-A model from a schematic, with embedded non-linear behavioural sources, is not automatic but is normally undertaken manually. This paper introduces a new approach to the generation of Verilog-A compact device models from Qucs circuit schematics using a purpose built analogue module synthesizer. To illustrate the properties and use of the Qucs Verilog-A module synthesiser, the text includes a number of semiconductor device modelling examples and in some cases compares their simulation performance with conventional behavioural device models.
