IPMSM Outer Loop Controller Evaluation

Control the rotor angular velocity in an interior permanent magnet synchronous machine (IPMSM) based electrical-traction drive. For evaluation of the outer loop velocity controller, the inner loop current controller is replaced by a three-phase controlled current source. An ideal torque source provides the load. The Scopes subsystem contains scopes that allow you to see the simulation results. The Control subsystem includes a PI-based outer loop controller. During the three-seconds simulation, the angular velocity demand is -1000, 2000, 3000, 4000, and then 5000 rpm.

Open Model

Differential Pair Amplifier

A differential pair amplifier circuit. The circuit can be used to explore the properties of a differential pair amplifier. The model can be tested using differential and common-mode inputs. The balanced output has zero gain in common-mode provided that the two transistors have identical properties.

Solar Cell Power Curve

Generate the power-voltage curve for a solar array. Understanding the power-voltage curve is important for inverter design. Ideally the solar array would always be operating at peak power given the irradiance level and panel temperature.

Linear Voltage Regulator with Feedback

A simple voltage regulator circuit constructed from discrete components. A fluctuating supply is modeled as 20V DC plus a 1V sinusoidal variation. The zener diode D1 sets the non-inverting input of the op-amp to 3.2V, and hence as the op-amp has a large gain, the op-amp inverting input and output are also at 3.2V. Hence the regulator voltage output is regulated to be 3.2*(1000+470)/470=10V. The NPN bipolar transistor is required to provide higher currents than is possible from a typical op-amp. The model can be used to check circuit operation, and to support selection of components to achieve the desired voltage regulation.
