Abstract A discrete-time-coupled state-dependent Riccati equation (CSDRE) control strategy is structured in this paper for synthesizing state feedback controllers satisfying the combined nonlinear quadratic regulator (NLQR) and H∞ robust control performance objectives. Under smoothness assumptions, the nonlinear plant dynamics can be formulated into state-dependent coefficient form through direct parameterization. By solving a pair of coupled state-dependent Riccati equations, the optimal stabilizing solutions can achieve inherent stability, nonlinear quadratic optimality, and H∞ disturbance attenuation performance. The established two-player Nash's game theory is utilized for developing both of the finite and infinite time optimal control laws. Furuta swing-up pendulum, a representative nonholonomic underactuated nonlinear system, is stabilized in real-time for validating the robustness and potential of proposed approach in mechatronics applications.

Electronic Throttle Control

This paper establishes the Simulink model of electronic throttle control system (ETCS) and designs the PID control program of it which based on D2P Motohawk platform. By simulation and experiments, it analyzes the response characteristic of ETCS and determines its algorithm. The PID control strategy based on D2P Motohawk is stable and reliable, and easily implemented in hardware, which improves the control performance of ETCS.
