“…With this in mind, this article is focused on describing the implementation of the novel multi-domain models and the VSD drive, which were developed using the Modelica modeling language [19] and are compatible with the Open-Instance Power System Library (OpenIPSL) [20]. The Modelica language is an object-oriented multi-domain modeling language used to simulate complex cyber-physical systems [21], which allows for model representation in the form of equations, and seamless creation and connection of components from multiple different domains.…”

This paper introduces an innovative method for characterizing, implementing, and validating both three-phase and single-phase induction motor models, accompanied by a variable speed drive model. The primary goal is to investigate interactions between the electrical power grid and other dynamic domains (e.g., thermofluidic) that impact motor/load drive behavior. Our approach involves establishing a mechanical interface based on a physically meaningful equation linking motor torque/speed to the electrical model in the phasor domain. This allows seamless integration of diverse domain subsystems into a unified multi-domain model using Modelica v4.0.0 and the OpenIPSL library v3.0.1, overcoming co-simulation limitations. The proposed model, which requires only one Modelica-compliant tool for simulation, introduces additional dynamics through the mechanical interface, enabling explicit simulation of load disturbances based on constitutive physics. This deepens our understanding of dynamic interactions between the electrical power domain and other subsystems connected through the motor. We detail the modeled components using mathematical equations and textual descriptions, emphasizing the Modelica modeling approach. Simulation examples validate the implementation, demonstrating the multi-domain modeling capabilities of the newly developed components.

“…Modelica language is an equation-based declarative modeling language proposed in 1997 to address the unified modeling and co-simulation of multi-domain physical systems, based on the generalization of many previous modeling languages. The non-causal declarative modeling method based on Modelica language is no longer based on assignment statements, but on mathematical equations, i.e., there is no need to artificially specify the data flow direction when modeling, and a fixed data flow direction will be automatically generated only when solving the problem [14]- [16], which has obvious advantages in dealing with complex systems such as quadrotor UAVs that are nonlinear, strongly coupled, and have multiple data flow directions. The MWorks modeling and simulation platform jointly launched by Huazhong University of Science and Technology and Suzhou Tongyuan Soft-control marks the realization of independent control of Modelica technology in China.…”

Due to the nonlinearity, underactuated, strong coupling, multi-data flow direction, and vulnerability to internal and external disturbances, the widely used PID control technology has been very difficult. Some emerging nonlinear control theory algorithms have good simulation performance, but they rely heavily on exact mathematical models, require a large amount of computation, and take a long time to solve. Therefore, based on the advantages of non-causal declarative modeling in Modelica language, this paper focuses on the analysis and implementation of the mechanism of observation, estimation, and compensation of nonlinear ADRC disturbances, PID-NLADRC linear nonlinear combined control strategy is designed to realize the flight control of a four-rotor UAV. The multi-target applications, such as fixed-point hover, cone spiral trajectory tracking and air obstacle avoidance fillet moment trajectory tracking, are verified respectively. The simulation results show that the designed PID-NLADRC control strategy has better performance than the Cascade PID control strategy in suppressing the fixed-point hover disturbance, it is fully verified that the PID-NLADRC control strategy has a smaller Euclidean range deviation and stronger disturbance rejection ability for tracking trajectories with different properties such as plane or space, smooth or transient, it can better meet the requirements of fast, accurate and robust flight control of four-rotor UAV.

The North American Electric Reliability Corporation (NERC) is expected to mandate model validation of power plant equipment in the near future. This will create a need to validate models for a large fleet of existing and future power plants. Historically, model validation of synchronous generators, excitation system, turbine governor, and other power system equipment has been conducted in diverse platforms. As a contribution to the power system model implementation using Modelica language and validation against commercial tools this work continues to develop power system component models and enriching the Open-Instance Power System Library (OpenIPSL). As a part of the development of OpenIPSL this paper describes the development of models used by North American utilities that follow NERC modeling requirements, including models of a synchronous generator, an excitation system, a turbine and governor using Modelica language in Dymola. The component implementation process is described and the validation of the models implemented in Modelica against PSS/E using both a single machine infinite bus (SMIB) and multi-machine system models is illustrated.
