In the field of high precision positioning control, the position servo system must be highly robust against disturbance torque. A Permanent Magnet Synchronous Motor (PMSM) has various torque ripple components that degrade control performance. A portion of the torque ripple is caused by the harmonic current. The torque ripple can be suppressed using a highly robust current control system. The remaining torque ripple is defined as the disturbance torque and is compensated for using a Disturbance OBserver (DOB). However, it is very difficult for a DOB to perform the appropriate compensation because it uses a low-pass filter to reduce noise. To obtain highly robust performance, this paper proposes a new position servo system using a disturbance torque hybrid observer and a current control system in the α − β stationary frame. In addition, this paper uses the torque ripple equation instead of a torque ripple table so as to reduce the amount of Digital Signal Processor (DSP) memory. The effectiveness of the proposed position servo system is confirmed using numerical and experimental results.

“…To achieve the abovementioned requirements, a proportional integral (PI) controller is usually used. However, fast transience [2] and a stable output voltage [3] cannot be obtained under uncertain disturbances. Several control solutions derived for clean energy systems have been reported, such as the wavelet transform technique [4], deadbeat control [5], and repetitive control [6], but they are difficult to realize and have complicated algorithms.…”

In this paper, a robust finite-time tracking control design for clean energy systems has been developed to maintain a low-total-harmonic-distortion output voltage and a fast dynamic response under various loads. The proposed control combines the properties of a fast-converging sliding mode control (FCSMC) and glowworm swarm optimization (GSO). The FCSMC has a finite system state convergence time unlike the infinite-time exponential convergence of classic sliding mode control, but chattering still occurs under a highly uncertain disturbance. Chattering causes high voltage harmonic distortion in a clean energy system's output. To effectively remove the chattering, the control gains of the FCSMC can be optimally tuned using the GSO. The experimental results obtained from a clean energy system controlled by a digital-signal-processing-based algorithm confirm that the proposed controller can provide a highquality AC output voltage. This paper will be of interest to designers of related clean energy applications because the proposed controller is easier to implement than prior technologies and has a higher tracking precision and quicker convergence speed.

The output of the controller is said to exceed the input limits of the plant being controlled when a control system operates in a non-linear region. This process is called the windup phenomenon. The windup phenomenon is not preferable in the control system because it leads to performance degradation, such as overshoot and system instability. Many anti-windup strategies involve switching, where the integral component differently operates between the linear and the non-linear states. The range of state for the non-overshoot performance is better illustrated by the boundary integral error plane than the proportional-integral (PI) plane in windup inspection. This study proposes a PI controller with a separate closed-loop integral controller and reference value set with respect to the input command and external torque. The PI controller is compared with existing conventional proportional integral, conditional integration, tracking back calculation, and integral state prediction schemes by using ScicosLab simulations. The controller is also experimentally verified on a direct current motor under no-load and loading conditions. The proposed controller shows a promising potential with its ability to eliminate overshoot with short settling time using the decoupling mode in both conditions.
