It is simple, computationally "light," and incredibly well-understood. You don't need a complex mathematical model of your motor to make it work. PID and Predictive Control of Electrical Drives...
Standard industrial applications where reliability and ease of tuning are more important than pushing the motor to its absolute physical limits. 2. The High-Performer: Model Predictive Control (MPC) Two heavyweights dominate the landscape: the classic control
In the world of electrical drives—the systems that power everything from industrial robots to electric vehicles—choosing the right control strategy is a high-stakes decision. Two heavyweights dominate the landscape: the classic control and the advanced Model Predictive Control (MPC) . 1. The Reliable Classic: PID Control often outperforming PID in dynamic precision.
It requires a high-performance processor and an accurate mathematical model of the drive. If your motor parameters change (like getting hot), the model might become inaccurate.
It handles constraints (like current or voltage limits) natively. It is also exceptionally fast at responding to sudden changes in load or speed, often outperforming PID in dynamic precision.
It struggles with "multi-variable" systems (like controlling torque and flux simultaneously) and doesn't handle physical limits—like voltage saturation—very gracefully.
