To overcome the defects of pure integrator initial value of the integral, the cumulative error and DC offset, permanent magnet synchronous motor stator flux observer method is proposed based on full-order state observer. The stator flux as state vector to construct the system state equation, the current as output vector to construct the system output equation, configuration observer poles proportional to the motor model pole, and use of the robust pole assignment algorithm in Matlab for

Pneumatic actuator system is inexpensive, high power to weight ratio, cleanliness and ease of maintenance make it’s a choice compared to hydraulic actuator and electromagnetic actuator. Nonetheless, the steady state error of the system is high due to the dead zone of the valve. In this paper, an Auto-Regressive with External Input (ARX) model structure is chosen to represent the pneumatic actuator system. The recursive least square method is used to estimate the model parameters. The pole
