Sure, here are some examples of use cases where MPC might be chosen over PID, and vice versa:
Use cases where MPC might be chosen over PID:

	1.	Processes with constraints: MPC can handle constraints on inputs and outputs, while PID cannot. For example, in chemical processes, it is often necessary to maintain certain safety constraints such as avoiding certain chemical reactions or ensuring certain product quality specifications, and MPC can be used to optimize control while meeting these constraints. 
	2.	Nonlinear systems: MPC can handle nonlinear systems, while PID is best suited for linear systems. For example, in HVAC systems, the nonlinear dynamics of heating and cooling systems can be better handled by MPC than by PID. 
	3.	Multivariable systems: MPC can handle multivariable systems, while PID is limited to SISO (single-input single-output) systems. For example, in a distillation column, multiple variables such as pressure, temperature, and flow rate need to be controlled simultaneously, and MPC can optimize control over all these variables. 


Use cases where PID might be chosen over MPC:

	1.	Simple systems: PID is simpler and easier to implement than MPC. For simple systems, PID can provide sufficient control performance with minimal computational overhead. 
	2.	Fast response: PID is faster than MPC in terms of response time, making it suitable for systems with fast dynamics or rapid changes in setpoints or disturbances. 
	3.	Real-time requirements: For real-time applications, PID may be preferred over MPC because it requires less computational overhead and can provide fast and robust control even in the presence of noise and uncertainties. 


In practice, the choice between MPC and PID will depend on several factors such as the complexity of the system, the performance requirements, the availability and accuracy of the model, and the computational resources available for control.
