Modelado físico

Modelice sistemas físicos utilizando el software de Simscape™

Para modelizar sistemas en el entorno de Simulink^®, puede utilizar el software de Simscape.

Simscape amplía Simulink con herramientas para modelizar sistemas que comprenden dominios mecánicos, eléctricos, hidráulicos y otros dominios físicos como redes físicas. Proporciona bloques de construcción fundamentales de estos dominios para crear modelos de componentes personalizados. El lenguaje de Simscape basado en MATLAB^® permite crear componentes, dominios y bibliotecas de modelado físico basados en texto.

Double Mass-Spring-Damper in Simulink and Simscape

Two models of a double mass-spring-damper, one using Simulink® input/output blocks and one using Simscape™ physical networks.

Permanent Magnet DC Motor

This model is based on a Faulhaber Series 0615 DC-Micromotor. The parameters values are set to match the 1.5V variant of this motor. The model uses these parameters to verify manufacturer-quoted no-load speed, no-load current, and stall torque.

Brayton Cycle (Gas Turbine) with Custom Components

Models a gas turbine auxiliary power unit (APU) based on the Brayton Cycle. The Compressor and Turbine blocks are custom components based on the Simscape™ Foundation Gas Library. The power input to the system is represented by heat injection into the combustor; actual combustion chemistry is not modeled. A single shaft connects the compressor and the turbine so that the power from the turbine drives the compressor. The APU is a free turbine that further expands the exhaust stream to produce output power.

Two-Phase Fluid Refrigeration

Models a vapor-compression refrigeration cycle using two-phase fluid components. The compressor drives the R-134a refrigerant through a condenser, an expansion valve, and an evaporator. The hot gas leaving the compressor condenses in the condenser via heat transfer to the environment. The pressure drops as the refrigerant passes through the expansion valve. The drop in pressure lowers the saturation temperature of the refrigerant. This enables it to boil in the evaporator as it absorbs heat from the refrigerator compartment. The refrigerant then returns to the compressor to repeat the cycle. The controller turns the compressor on and off to maintain the refrigerator compartment temperature within a band around the desired temperature.
