Applications d'automatisation industrielle

Extends the Smart4i virtual commissioning applications to accommodate robot dynamics in the system framework to automate assembly line operation. This example models and controls the dynamics of robots in the assembly line, which helps develop a more realistic simulation environment. The virtual assembly line consists of four components: two robotic workcells, connected by a shuttle track and a conveyor belt. The first robot, Robot 1, is a Comau Racer V3 and places cups onto the shuttle. The second robot, Robot 2, is a Mitsubishi RV-4F and places balls in the cups. The shuttle track system consists of four shuttles which continuously move to Robot 1, then to Robot 2, followed by a slider. A slider then delivers those cups containing balls to a container. For a detailed system overview, see Automate Virtual Assembly Line with Two Robotic Workcells (Robotics System Toolbox).

Use anti-windup schemes to prevent integration wind-up in PID controllers when the actuators are saturated. The PID Controller block in Simulink® features two built-in anti-windup methods, back-calculation and clamping, as well as a tracking mode to handle more complex industrial scenarios. The PID Controller block supports several features that allow it to handle controller windup issues under commonly encountered industrial scenarios.

Achieve bumpless control transfer when switching from manual control to proportional integral derivative (PID) control. The model uses the PID Controller block in Simulink® to control a first-order process with dead-time.

Regulate the speed of an electric motor using two degree-of-freedom PID control with set-point weighting. This model uses the PID Controller (2DOF) block. The model changes the setpoint values between 60 and 30 rpm. To convert the units to rad/s for use in the PID controller, the model uses a Signal Conversion block.
