The Proportional, Integral and Derivative –PID– controller is the most widely used
controller in industrial applications. Since its first appearance in the late nineteen century,
it had attracted researchers from all over the world because of its simplicity and
the ability to provide an excellent control performance. The PID controller now represents
more than ninety percent of the controllers used in the market.
This book is a result of contributions and inspirations from many researchers worldwide
in the field of control engineering.
Assume that gi (x) = 1 (hence gk (x) = 0, k = i), update the expert i based on output error. Update gating network so that gi (x) is even closer to unity. Alternatively, a batch training method can be adopted: 1. Apply a clustering algorithm to cluster the set of training samples into n clusters. Use the membership information to train the gating network. 2. Assign each cluster to an expert module and train the corresponding expert module. 3. Fine-tune the performance using gradient-based learning. Note that the function of the gating network is to partition the feature...
Semi-active (SA) suspensions are those which otherwise passively generated damping or spring
forces modulated according to a parameter tuning policy with only a small amount of control effort.
SA suspensions, as their name implies, fill the gap between purely passive and fully active suspensions
and offer the reliability of passive systems, yet maintain the versatility and adaptability of
fully active devices.
