Linear Electric Actuator (Implementation Model)

This linear actuator consists of a DC motor driving a worm gear which in turn drives a lead screw to produce linear motion. The actuator is controlled with an inner-loop current controller, and outer-loop speed controller. This is a detailed model that includes quantization effects of the Hall-effect sensor and the implementation of the control in analog electronics. Optionally, the implementation detail of the PWM & H-Bridge subsystem can be included by right clicking on the block and selecting the Implementation option from the Block Choice menu. The model will run slowly in this case due to the 10KHz PWM waveform and is intended for validation only. The Linear Electric Actuator (System- Level Model) shows an equivalent system-level model suitable for tasks where simulation speed is important.
