I'm a final year electrical engineering student. Currently I'm doing FYP on the topic Active suspension systems. Since this topic is also related to the automotive engineering, I'm not sure how to start my project. According to my supervisor I have to design the system and the end come out with the hardware. Until now I only know what are the components involve in the active suspension systems but that all are used in the industry and the components are very expensive. I would be happy if anyone can help me to find the suitable components as stated below for a cheaper price

microcontrollers
actuators

Thanx in advance.
