Actuator Optimization and Fuzzy Control in Mechatronics

WithH. Marzi

Summary

In this chapter, the characteristics of multi-input–output mechatronic systems are described, and application of fuzzy controllers to stabilize nonlinear multivariant systems is examined. The ability of different types of fuzzy controllers with respect to the number of inputs is investigated. The problem of balancing an inverted pendulum on a moving cart is simulated to demonstrate the performance of fuzzy control. Actuator optimization is an important step in the design optimization of a mechatronic system. As an exercise toward this goal, a mathematical model of a DC motor actuator is incorporated to optimize the selection of the actuator for improving the dynamic performance.
