What is the main difference in design of control system for aerodynamic system and electrical system?

Design of control system for electrical system like speed control is simple and easy when compared to aerodynamic system like MISSILE CONTROL. The main difference is that the electrical system are static where aerodynamics system are dynamic, in simple the co-efficient s  of transfer function are CONSTANT for electrical system where the same is varying for aerodynamic system. So design of controller for these dynamic system is tedious job. Here comes the new concept,generally we wont see in electrical control, the gain scheduling.In gain scheduling we find the transfer function of system at different operating points and we schedule gain of controller for different operating point.By doing this we can control the dynamic system especially aerodynamic systems like missiles.
