Direct Policy Optimization using Deterministic Sampling and Collocation
Taylor A. Howell, Chunjiang Fu, Zachary Manchester
We present an approach for approximately solving discrete-time stochastic optimal-control problems by combining direct trajectory optimization, deterministic sampling, and policy o…

Phase resetting and intermittent control at critical edge of stability as major mechanisms of fractality in human gait cycle variability
Chunjiang Fu, Yasuyuki Suzuki, Pietro Morasso +1
The fractality of human gait, namely, the long-range correlation that characterizes scale-free fluctuations of gait descriptors, such as the stride intervals during steady-state wa…

Extending iLQR method with control delay
Cheng Ju, Yan Qin, Chunjiang Fu
Iterative linear quadradic regulator(iLQR) has become a benchmark method to deal with nonlinear stochastic optimal control problem. However, it does not apply to delay system. In t…
