We present a scalable and tunable control design for controlling elevator vertical motion for ultra high-rise buildings. Scalability is desirable to enable customization to any hoistway while tunability enables periodic adjustments to normal wear and tear. We accomplish these objectives by first validating a scalable lumped parameter model that is based on a few prominent features in the vertical dynamics. A tunable controller based only on these features is developed and through simulations we show that the controller meets a set of standardized elevator performance tests while maintaining global exponential stability.
