Partial Differential Equations (PDEs) are mathematical tools used to describe a wide range of physical phenomena, from fluid dynamics and heat transfer to quantum mechanics. Understanding and controlling systems governed by PDEs is of utmost importance in various scientific and engineering fields.
The Challenge:
One of the fundamental challenges in PDE theory is the controllability problem. Given a system modeled by a PDE, the controllability problem seeks to find appropriate control strategies that can steer the system from an initial state to a desired target state within a given time frame. In simpler terms, it deals with the question of how to manipulate the system's inputs or boundary conditions to achieve a desired outcome.
Multiplicative Forces:
Controlling systems governed by PDEs becomes especially complex when we introduce multiplicative forces into the equation. Multiplicative forces are non-linear terms that depend not only on the state variables but also on the control inputs, making the analysis and control design more challenging.
